+# JNI Mockability Design - Clean Interface Abstraction
+
+**Goal:** Make all native calls mockable for unit testing without breaking existing API
+
+---
+
+## Design: Internal JniAdapter with Package-Private Injection
+
+### 1. Create JniAdapter Interface (Package-Private)
+
+```java
+package com.axonops.libre2.jni;
+
+/**
+ * Adapter interface for RE2 JNI operations.
+ * Package-private for testing - not part of public API.
+ */
+interface JniAdapter {
+ // Pattern lifecycle
+ long compile(String pattern, boolean caseSensitive);
+ void freePattern(long handle);
+ boolean patternOk(long handle);
+ String getError();
+ String getPattern(long handle);
+ int numCapturingGroups(long handle);
+ long patternMemory(long handle);
+
+ // Matching operations
+ boolean fullMatch(long handle, String text);
+ boolean partialMatch(long handle, String text);
+ boolean fullMatchDirect(long handle, long address, int length);
+ boolean partialMatchDirect(long handle, long address, int length);
+
+ // Bulk operations
+ boolean[] fullMatchBulk(long handle, String[] texts);
+ boolean[] partialMatchBulk(long handle, String[] texts);
+ boolean[] fullMatchDirectBulk(long handle, long[] addresses, int[] lengths);
+ boolean[] partialMatchDirectBulk(long handle, long[] addresses, int[] lengths);
+
+ // Capture groups
+ String[] extractGroups(long handle, String text);
+ String[][] extractGroupsBulk(long handle, String[] texts);
+ String[] extractGroupsDirect(long handle, long address, int length);
+ String[][] extractGroupsDirectBulk(long handle, long[] addresses, int[] lengths);
+ String[][] findAllMatches(long handle, String text);
+ String[][] findAllMatchesDirect(long handle, long address, int length);
+ String[] getNamedGroups(long handle);
+
+ // Replace operations
+ String replaceFirst(long handle, String text, String replacement);
+ String replaceAll(long handle, String text, String replacement);
+ String[] replaceAllBulk(long handle, String[] texts, String replacement);
+ String replaceFirstDirect(long handle, long address, int length, String replacement);
+ String replaceAllDirect(long handle, long address, int length, String replacement);
+ String[] replaceAllDirectBulk(long handle, long[] addresses, int[] lengths, String replacement);
+}
+```
+
+### 2. Production Implementation (Package-Private)
+
+```java
+package com.axonops.libre2.jni;
+
+/**
+ * Production JNI adapter - delegates directly to RE2NativeJNI.
+ * Package-private - not part of public API.
+ */
+class DirectJniAdapter implements JniAdapter {
+
+ // Singleton instance
+ static final DirectJniAdapter INSTANCE = new DirectJniAdapter();
+
+ private DirectJniAdapter() {
+ // Private constructor
+ }
+
+ @Override
+ public long compile(String pattern, boolean caseSensitive) {
+ return RE2NativeJNI.compile(pattern, caseSensitive);
+ }
+
+ @Override
+ public void freePattern(long handle) {
+ RE2NativeJNI.freePattern(handle);
+ }
+
+ // ... delegate all 29 methods to RE2NativeJNI
+}
+```
+
+### 3. Pattern Internal Field (Package-Private Injection Point)
+
+```java
+package com.axonops.libre2.api;
+
+public final class Pattern implements AutoCloseable {
+
+ // Package-private for testing - production uses singleton
+ final JniAdapter jni;
+
+ private final long nativeHandle;
+ private final String pattern;
+ // ... other fields
+
+ // PRIVATE constructor - used internally
+ private Pattern(JniAdapter jni, String pattern, boolean caseSensitive, PatternCache cache) {
+ this.jni = jni;
+ this.pattern = pattern;
+ this.cache = cache;
+
+ // Compile using adapter
+ long handle = jni.compile(pattern, caseSensitive);
+ if (handle == 0 || !jni.patternOk(handle)) {
+ String error = jni.getError();
+ throw new PatternCompilationException("Failed to compile pattern: " + error);
+ }
+ this.nativeHandle = handle;
+ // ... rest of initialization
+ }
+
+ // PUBLIC API - unchanged, uses production adapter
+ public static Pattern compile(String pattern) {
+ return compile(pattern, true);
+ }
+
+ public static Pattern compile(String pattern, boolean caseSensitive) {
+ // Production code uses singleton DirectJniAdapter
+ return compile(pattern, caseSensitive, DirectJniAdapter.INSTANCE);
+ }
+
+ // PACKAGE-PRIVATE for testing - inject mock adapter
+ static Pattern compile(String pattern, boolean caseSensitive, JniAdapter jni) {
+ PatternCache cache = getGlobalCache();
+ // ... cache lookup logic
+ return new Pattern(jni, pattern, caseSensitive, cache);
+ }
+
+ // All operations use this.jni instead of RE2NativeJNI directly
+ public boolean match(String input) {
+ checkNotClosed();
+ Objects.requireNonNull(input, "input cannot be null");
+
+ long startNanos = System.nanoTime();
+ boolean result = jni.fullMatch(nativeHandle, input); // Uses adapter!
+ long durationNanos = System.nanoTime() - startNanos;
+
+ // ... metrics recording
+ return result;
+ }
+
+ // ... all other methods use this.jni
+}
+```
+
+### 4. Test Usage - Clean and Powerful
+
+```java
+package com.axonops.libre2.api;
+
+import com.axonops.libre2.jni.JniAdapter;
+import org.junit.jupiter.api.Test;
+import org.mockito.Mockito;
+
+import static org.assertj.core.api.Assertions.*;
+import static org.mockito.Mockito.*;
+
+class PatternUnitTest {
+
+ @Test
+ void testMatch_callsCorrectJniMethod() {
+ // Create mock adapter
+ JniAdapter mockJni = mock(JniAdapter.class);
+
+ // Setup expectations
+ when(mockJni.compile("test\\d+", true)).thenReturn(12345L);
+ when(mockJni.patternOk(12345L)).thenReturn(true);
+ when(mockJni.numCapturingGroups(12345L)).thenReturn(0);
+ when(mockJni.patternMemory(12345L)).thenReturn(1024L);
+ when(mockJni.fullMatch(12345L, "test123")).thenReturn(true);
+
+ // Create pattern with mock adapter (package-private method)
+ Pattern pattern = Pattern.compile("test\\d+", true, mockJni);
+
+ // Execute
+ boolean result = pattern.match("test123");
+
+ // Verify
+ assertThat(result).isTrue();
+ verify(mockJni).compile("test\\d+", true);
+ verify(mockJni).fullMatch(12345L, "test123");
+ verifyNoMoreInteractions(mockJni);
+ }
+
+ @Test
+ void testReplaceAll_callsCorrectJniMethod() {
+ JniAdapter mockJni = mock(JniAdapter.class);
+
+ when(mockJni.compile("\\d+", true)).thenReturn(67890L);
+ when(mockJni.patternOk(67890L)).thenReturn(true);
+ when(mockJni.numCapturingGroups(67890L)).thenReturn(0);
+ when(mockJni.patternMemory(67890L)).thenReturn(512L);
+ when(mockJni.replaceAll(67890L, "test123", "XXX")).thenReturn("testXXX");
+
+ Pattern pattern = Pattern.compile("\\d+", true, mockJni);
+ String result = pattern.replaceAll("test123", "XXX");
+
+ assertThat(result).isEqualTo("testXXX");
+ verify(mockJni).replaceAll(67890L, "test123", "XXX");
+ }
+
+ @Test
+ void testBulkMatch_callsCorrectBulkJniMethod() {
+ JniAdapter mockJni = mock(JniAdapter.class);
+
+ when(mockJni.compile("test", true)).thenReturn(11111L);
+ when(mockJni.patternOk(11111L)).thenReturn(true);
+ when(mockJni.numCapturingGroups(11111L)).thenReturn(0);
+ when(mockJni.patternMemory(11111L)).thenReturn(256L);
+
+ String[] inputs = {"test1", "test2", "other"};
+ boolean[] expected = {true, true, false};
+ when(mockJni.fullMatchBulk(11111L, inputs)).thenReturn(expected);
+
+ Pattern pattern = Pattern.compile("test", true, mockJni);
+ boolean[] results = pattern.matchAll(inputs);
+
+ assertThat(results).isEqualTo(expected);
+ verify(mockJni).fullMatchBulk(11111L, inputs);
+ }
+}
+```
+
+---
+
+## Benefits of This Design
+
+### ✅ 1. Public API Unchanged
+```java
+// Users still write this - no breaking changes
+Pattern p = Pattern.compile("test\\d+");
+boolean match = p.match("test123");
+```
+
+### ✅ 2. Full Test Control
+```java
+// Tests can inject mock and verify exact calls
+JniAdapter mock = mock(JniAdapter.class);
+Pattern p = Pattern.compile("test", true, mock);
+verify(mock).fullMatch(eq(12345L), eq("test123"));
+```
+
+### ✅ 3. Package-Private Design
+- `JniAdapter` interface is NOT public
+- `DirectJniAdapter` is NOT public
+- Only `Pattern.compile(pattern, caseSensitive, JniAdapter)` is package-private
+- Tests in same package can access it
+- Users cannot misuse it
+
+### ✅ 4. Zero Runtime Overhead
+- Production code uses singleton `DirectJniAdapter.INSTANCE`
+- No interface overhead (JIT inlines static final calls)
+- Same performance as direct static calls
+
+### ✅ 5. Comprehensive Test Coverage
+Can now unit test:
+- ✅ Parameter validation before JNI calls
+- ✅ Metrics recording logic
+- ✅ Resource tracking
+- ✅ Error handling paths
+- ✅ Bulk operation batching logic
+- ✅ DirectByteBuffer address extraction
+- ✅ Cache interaction logic
+
+---
+
+## Implementation Strategy
+
+### Phase 2A: Create Abstraction (Before Test Migration)
+1. Create `JniAdapter` interface (package-private)
+2. Create `DirectJniAdapter` implementation (package-private)
+3. Update `Pattern` to use `jni` field instead of `RE2NativeJNI` static calls
+4. Update `Matcher`, `RE2` similarly
+5. Run full integration test suite - should all pass (no behavior change)
+
+### Phase 2B: Test Migration (With Mockability)
+6. Create new unit tests using mock JniAdapter
+7. Migrate existing tests to appropriate directories
+8. Verify all tests still pass
+

+## Example: Testing Metrics Recording Without Native Library
+
+```java
+@Test
+void testMatchAll_recordsCorrectMetrics() {
+ JniAdapter mockJni = mock(JniAdapter.class);
+ RE2MetricsRegistry mockMetrics = mock(RE2MetricsRegistry.class);
+
+ // Setup
+ when(mockJni.compile("test", true)).thenReturn(123L);
+ when(mockJni.patternOk(123L)).thenReturn(true);
+ when(mockJni.numCapturingGroups(123L)).thenReturn(0);
+ when(mockJni.patternMemory(123L)).thenReturn(100L);
+ when(mockJni.fullMatchBulk(eq(123L), any())).thenReturn(new boolean[]{true, false, true});
+
+ // Create pattern with mock metrics
+ PatternCache cache = new PatternCache(RE2Config.builder()
+ .metricsRegistry(mockMetrics)
+ .build());
+ Pattern pattern = Pattern.compile("test", true, mockJni, cache);
+
+ // Execute
+ String[] inputs = {"test1", "test2", "test3"};
+ pattern.matchAll(inputs);
+
+ // Verify metrics (without running native code!)
+ verify(mockMetrics).incrementCounter("re2.matching.operations.total.count", 3);
+ verify(mockMetrics).incrementCounter("re2.matching.bulk.operations.total.count", 1);
+ verify(mockMetrics).incrementCounter("re2.matching.bulk.items.total.count", 3);
+ verify(mockMetrics, times(2)).recordTimer(eq("re2.matching.latency"), anyLong());
+}
+```
+
+---
+
+## Decision Point
+
+**Do you approve this design?**
+
+If yes, I'll implement it in Phase 2A before any test migration. This gives us:
+- ✅ Full mockability of all native calls
+- ✅ Ability to assert correct JNI parameters
+- ✅ Unit tests for all business logic
+- ✅ No public API changes
+- ✅ No runtime overhead
+
+**Alternative:** If you have a different approach in mind, I'm open to it. The key requirement is: **mock all native calls to verify correct parameters**.

+ */
+ static final DirectJniAdapter INSTANCE = new DirectJniAdapter();
+
+ private DirectJniAdapter() {
+ // Private constructor - singleton pattern
+ }
+
+ // ========== Pattern Lifecycle ==========
+
+ @Override
+ public long compile(String pattern, boolean caseSensitive) {
+ return RE2NativeJNI.compile(pattern, caseSensitive); // ✅ Same package - accessible
+ }

+ }
+
+ // ... delegate all 29 methods to RE2NativeJNI
+
+ // All calls work because DirectJniAdapter is in same package as RE2NativeJNI
+}
+```
+
+### 4. Pattern Uses JniAdapter (Different Package)
+
+```java
+package com.axonops.libre2.api;
+
+import com.axonops.libre2.jni.JniAdapter;
+import com.axonops.libre2.jni.DirectJniAdapter;

+ }
+
+ // PUBLIC API - uses production singleton adapter

+ }
+
+ public static Pattern compile(String pattern, boolean caseSensitive) {

+ }
+
+ // PACKAGE-PRIVATE - tests inject mock adapter
+ static Pattern compile(String pattern, boolean caseSensitive, JniAdapter jni) {
+ PatternCache cache = getGlobalCache();
+ return new Pattern(jni, pattern, caseSensitive, cache);
+ }
+
+ // All operations use this.jni (enforced at compile-time)
+ public boolean match(String input) {
+ checkNotClosed();
+ Objects.requireNonNull(input, "input cannot be null");
+
+ long startNanos = System.nanoTime();
+ boolean result = jni.fullMatch(nativeHandle, input); // ✅ Must use adapter
+ // boolean result = RE2NativeJNI.fullMatch(...); // ❌ COMPILE ERROR!
+ long durationNanos = System.nanoTime() - startNanos;
+
+ // ... metrics
+ return result;
+ }
+}
+```
+
+---
+
+## Benefits of Package-Private RE2NativeJNI
+
+### ✅ 1. Compile-Time Enforcement
+
+**Before (public RE2NativeJNI):**
+```java
+// Pattern.java - could accidentally bypass abstraction
+boolean result = RE2NativeJNI.fullMatch(handle, text); // ✅ Compiles (bad design)
+```
+
+**After (package-private RE2NativeJNI):**
+```java
+// Pattern.java - MUST use adapter
+boolean result = RE2NativeJNI.fullMatch(handle, text); // ❌ COMPILE ERROR!
+boolean result = jni.fullMatch(handle, text); // ✅ Must use interface
+```
+
+### ✅ 2. Clear Separation of Concerns
+
+```
+com.axonops.libre2.jni/ (JNI layer - isolated)
+├── RE2NativeJNI.java (package-private native methods)
+├── JniAdapter.java (package-private interface)
+└── DirectJniAdapter.java (package-private singleton)
+
+com.axonops.libre2.api/ (Public API - uses interface)
+├── Pattern.java (uses JniAdapter, cannot access RE2NativeJNI)
+├── Matcher.java (uses JniAdapter, cannot access RE2NativeJNI)
+└── RE2.java (uses JniAdapter, cannot access RE2NativeJNI)
+```
+
+### ✅ 3. Impossible to Bypass Abstraction
+
+**Users cannot do this:**
+```java
+// This would compile if RE2NativeJNI were public
+long handle = RE2NativeJNI.compile("test", true); // ❌ COMPILE ERROR - package-private
+RE2NativeJNI.freePattern(handle); // ❌ COMPILE ERROR - package-private
+```
+
+**Must use public API:**
+```java
+Pattern pattern = Pattern.compile("test"); // ✅ Only way
+```
+
+### ✅ 4. Tests Still Work (Same Package)
+
+```java
+package com.axonops.libre2.api; // Different package from RE2NativeJNI
+
+import com.axonops.libre2.jni.JniAdapter;
+import org.mockito.Mockito;
+
+class PatternUnitTest {
+ @Test
+ void testMatch() {
+ JniAdapter mock = mock(JniAdapter.class);
+ when(mock.compile("test", true)).thenReturn(123L);
+ when(mock.fullMatch(123L, "test")).thenReturn(true);
+
+ Pattern p = Pattern.compile("test", true, mock); // ✅ Package-private method
+ boolean result = p.match("test");
+
+ verify(mock).fullMatch(123L, "test"); // ✅ Can verify interface calls
+ }
+}
+```
+
+---
+
+## Implementation Changes
+
+### Change 1: RE2NativeJNI Visibility
+
+```java
+// BEFORE (current):
+public final class RE2NativeJNI {
+ public static native long compile(String pattern, boolean caseSensitive);
+ // ...
+}
+
+// AFTER (package-private):
+final class RE2NativeJNI {
+ static native long compile(String pattern, boolean caseSensitive);
+ // ... all methods package-private
+}
+```
+
+### Change 2: Pattern/Matcher/RE2 MUST Use JniAdapter
+
+```java
+// BEFORE:
+boolean result = RE2NativeJNI.fullMatch(handle, text);
+
+// AFTER:
+boolean result = jni.fullMatch(handle, text);
+```
+
+**Compiler enforces this change** - any direct RE2NativeJNI calls in Pattern/Matcher/RE2 will fail to compile.
+
+---
+
+## Summary
+
+**Your suggestion is perfect!** Making RE2NativeJNI package-private:
+
+1. ✅ **Works with native methods** - Visibility doesn't affect JNI name mangling
+2. ✅ **Enforces abstraction** - Compile error if bypassed
+3. ✅ **Zero runtime cost** - Same performance as direct calls
+4. ✅ **Enables testing** - Mock JniAdapter interface
+5. ✅ **Clean architecture** - JNI layer isolated in one package
+
+**Next Steps:**
+1. Implement package-private RE2NativeJNI
+2. Create JniAdapter interface and DirectJniAdapter
+3. Update Pattern/Matcher/RE2 to use JniAdapter field
+4. Verify all existing tests pass (integration tests unchanged)
+5. Add new unit tests with mocked JniAdapter
+
+**Approved for implementation?**

-# JNI Optimization Attempt - Conclusion
-
-**Date:** 2025-11-25
-**Branch:** feature/jni-optimization (deleted)
-**Outcome:** ❌ **Reverted** - No performance gain, Unicode encoding issues
-**Token Used:** 450k / 1M
-**Decision:** Keep existing GetStringUTFChars approach
-
----
-
-## Executive Summary
-
-Attempted to optimize JNI String transfer based on RocksDB research (GetByteArrayRegion vs GetStringUTFChars). **Optimization failed** due to:
-
-1. **No Performance Improvement:** String→byte[] conversion overhead canceled out JNI gains
-2. **Modified UTF-8 Mismatch:** Pattern compilation uses Modified UTF-8, inputs use Standard UTF-8
-3. **Edge Case Bugs:** Empty strings, null handling, Unicode characters all broke
-
-**Baseline:** 2.76ms for 10k strings, 3.6M matches/sec
-**Optimized:** 2.79ms for 10k strings, 3.5M matches/sec (SLOWER)
-
-**RocksDB's findings don't apply when you START with Java Strings** - the conversion cost dominates.
-
----
-
-## What Was Attempted
-
-### Implementation
-
-**Added 10 new JNI methods:**
-- fullMatchBytes, partialMatchBytes
-- fullMatchBulkBytes, partialMatchBulkBytes
-- extractGroupsBytes, extractGroupsBulkBytes
-- findAllMatchesBytes
-- replaceFirstBytes, replaceAllBytes, replaceAllBulkBytes
-
-**Modified 9 Pattern.java methods** to convert String→byte[] before JNI call
-
-**C++ Implementation:**
-- Used GetByteArrayRegion (recommended by RocksDB)
-- Stack allocation for small strings (<8KB)
-- Heap allocation for large strings
-
----
-
-## Why It Failed
-
-### 1. String→byte[] Conversion Overhead
-
-**RocksDB Context:**
-- They START with byte[] data (database keys/values)
-- Direct byte[] → JNI is fast
-- String → byte[] → JNI is slow (extra conversion)
-
-**Our Context:**
-- We START with Java Strings (user regex patterns)
-- Must convert String → byte[] in Java
-- Conversion cost = 100-200ns per string
-- JNI improvement = 300ns (GetStringUTFChars) → 100ns (GetByteArrayRegion) = 200ns saved
-- **Net: Lost 100-200ns, gained 200ns = WASH**
-
-### 2. Modified UTF-8 vs Standard UTF-8 Mismatch
-
-**Problem:**
-```java
-// Pattern compilation
-Pattern.compile("😀") // Uses GetStringUTFChars → Modified UTF-8 in RE2
-
-// Input matching
-pattern.matchAll(["test😀test"]) // Uses getBytes(UTF_8) → Standard UTF-8
-```
-
-**Result:** Pattern and input use different UTF-8 encodings
-
-**Impact:**
-- ASCII: Works (same in both encodings)
-- BMP Unicode (Chinese, Arabic): **Should work but failed** (unknown cause)
-- Emoji/Supplementary (U+10000+): Definitely broken (6 bytes vs 4 bytes)
-
-### 3. StringPiece Lifetime Bugs
-
-**Issue:** StringPiece points to temporary buffer:
-```cpp
-jbyte stackBuf[8192];
-env->GetByteArrayRegion(bytes, 0, length, stackBuf);
-re2::StringPiece input((const char*)stackBuf, length);
-// ... Match happens ...
-// stackBuf goes out of scope
-// Later: groups[i].data() points to freed memory!
-```
-
-**Fix Required:** Immediately convert to std::string after Match()
-
-**3 rounds of bugs:**
-- Round 1: StringPiece lifetime in findAllMatchesBytes
-- Round 2: StringPiece lifetime in extractGroupsBytes
-- Round 3: Empty string handling (groups[0] == null)
-- Round 4: Null elements in String[] arrays
-- Round 5: Unicode encoding failures
-
-**Too many edge cases** for marginal/zero gain.
-
----
-
-## Performance Measurements
-
-### Baseline (GetStringUTFChars)
-```
-Filter Performance (10,000 strings):
-- Duration: 2.76 ms
-- Throughput: 3,628,117 matches/sec
-- Per-match: 0.276 μs
-
-Map Filter (10,000 entries):
-- Duration: 4.15 ms
-
-Bulk vs Individual:
-- Bulk: 2.32 ms
-- Individual: 2.57 ms
-- Speedup: 1.1x
-```
-
-### Optimized (GetByteArrayRegion + String→byte[])
-```
-Filter Performance (10,000 strings):
-- Duration: 2.79 ms (SLOWER!)
-- Throughput: 3,585,086 matches/sec
-- Per-match: 0.279 μs
-
-Map Filter (10,000 entries):
-- Duration: 4.51 ms (SLOWER!)
-```
-
-**Net Impact:** -3% performance (worse than baseline)
-
----
-
-## Lessons Learned
-
-### When RocksDB Optimizations Apply
-
-✅ **Good for:**
-- Native data sources (byte[] from databases, files, network)
-- Pre-existing byte[] arrays
-- DirectByteBuffer (zero-copy)
-
-❌ **Bad for:**
-- Java String inputs (must convert first)
-- Mixed UTF-8 encodings (Modified vs Standard)
-- Simple/short strings (conversion overhead dominates)
-
-### What Actually Works in Our Library
-
-✅ **DirectByteBuffer zero-copy paths** - Already implemented, optimal
-✅ **Bulk APIs** - Single JNI crossing for many operations
-✅ **Pattern caching** - Avoid recompilation
-✅ **GetStringUTFChars** - JVM optimizes this well, handles all Unicode correctly
-
----
-
-## Technical Details
-
-### Modified UTF-8 (GetStringUTFChars)
-- NULL: 0xC0 0x80 (not 0x00)
-- Supplementary chars (U+10000+): 6 bytes (surrogate pair encoding)
-- Used by JNI for all String operations
-
-### Standard UTF-8 (getBytes(UTF_8))
-- NULL: 0x00
-- Supplementary chars: 4 bytes (direct encoding)
-- Used by Files, Network, StandardCharsets
-
-**Pattern compiled with one, input with the other = mismatch**
-
----
-
-## Recommendations
-
-### For libre2-java
-
-1. **Keep existing implementation** - GetStringUTFChars throughout
-2. **Focus on bulk APIs** - This is where real gains are (already have it)
-3. **Keep DirectByteBuffer paths** - Already optimal for off-heap data
-4. **Don't add byte[] variants** - No benefit, adds complexity
-
-### For Future Optimization Attempts
-
-1. **Measure first** - Establish baseline before coding
-2. **Consider the full path** - String→byte[] conversion isn't free
-3. **Test Unicode** - GetStringUTFChars handles all cases correctly
-4. **Start small** - One method, measure, then expand if beneficial
-
----
-
-## What to Keep
-
-**Analysis Documents (valuable):**
-- ✅ JNI_OPTIMIZATION_ANALYSIS.md - Good reference for future
-- ✅ BASELINE_PERFORMANCE.md - Performance baseline documented
-
-**Code:**
-- ❌ byte[] JNI methods - Removed (no benefit)
-- ❌ Native implementations - Removed (bugs, no gain)
-- ✅ Existing GetStringUTFChars code - Keep as-is
-
----
-
-## Final Status
-
-**Branch:** development
-**Tests:** 459/459 passing ✅
-**Build:** SUCCESS ✅
-**Performance:** Baseline maintained (3.6M matches/sec)
-
-**Feature branch deleted:** feature/jni-optimization
-**Time invested:** ~4 hours
-**Outcome:** Valuable learning, correct decision to revert
-
----
-
-## Next Steps
-
-**Library is production-ready** with current implementation:
-- ✅ 459 tests passing
-- ✅ 55 metrics instrumented
-- ✅ All phases (0-5) complete
-- ✅ Zero-copy DirectByteBuffer support
-- ✅ Comprehensive bulk APIs
-
-**Potential areas for improvement:**
-1. Documentation (QUICKSTART.md, examples)
-2. Version 1.0.0 release preparation
-3. Additional integration tests
-4. Performance profiling in real Cassandra workload
-5. JMH micro-benchmarks for specific operations
-
-**Recommendation:** Focus on documentation and release preparation, not micro-optimizations.

+# Mockability and Unit Test Strategy Assessment
+
+**Date:** 2025-11-26
+**Purpose:** Corrected analysis of what can be unit tested without native library
+
+---
+
+## The Static Method Problem
+
+**All JNI methods are `public static native`:**
+```java
+public class RE2NativeJNI {
+ public static native long compile(String pattern, boolean caseSensitive);
+ public static native void freePattern(long handle);
+ public static native boolean fullMatch(long handle, String text);
+ // ... 26 more static native methods
+}
+```
+
+**Implications:**
+- Cannot use traditional interface-based dependency injection
+- Mocking static methods requires:
+ - **Mockito 3.4+ with mockito-inline** (can mock statics in JUnit 5)
+ - **PowerMock** (deprecated, poor JUnit 5 support)
+- Most Pattern/Matcher/RE2 logic IS the native call - minimal business logic to test
+
+---
+
+## What's Actually Unit-Testable?
+
+### Files That DON'T Call Native Code (16 files)
+
+**Pure Java, No Native Dependencies:**
+
+#### 1. Configuration & Builders ✅
+- `RE2Config.java` - Builder pattern, validation
+- `MetricNames.java` - String constants
+- **Already tested:** `ConfigurationTest.java` (14 tests) ✅
+
+#### 2. Metrics Abstractions ✅
+- `RE2MetricsRegistry.java` - Interface
+- `NoOpMetricsRegistry.java` - No-op implementation
+- `DropwizardMetricsAdapter.java` - Adapter (can mock MetricRegistry)
+- **Already tested:** `TimerHistogramTest.java` (4 tests) ✅
+- **Testable:** Adapter logic without Dropwizard
+
+#### 3. Exception Classes ✅
+- `RE2Exception.java` (sealed base)
+- `PatternCompilationException.java`
+- `NativeLibraryException.java`
+- `ResourceException.java`
+- `RE2TimeoutException.java`
+- **Already tested:** Implicitly in integration tests
+- **Testable:** Exception hierarchies, messages, causes
+
+#### 4. Value Objects ✅
+- `MatchResult.java` - Holds capture groups, implements AutoCloseable
+- `CacheStatistics.java` - Immutable stats record
+- **Already tested:** `CaptureGroupsTest.java` (31 tests) ✅
+- **Testable:** MatchResult lifecycle, closed state checking
+
+#### 5. Utilities ✅
+- `PatternHasher.java` - Pattern hash computation
+- `ResourceTracker.java` - Resource tracking logic
+- **Testable:** Hash consistency, resource accounting
+
+#### 6. Cache Logic (Partially Testable)
+- `PatternCache.java` - Cache management
+- `IdleEvictionTask.java` - Background eviction
+- **Issue:** Cache stores compiled Patterns (which need native library)
+- **Mockable:** LRU eviction logic, idle timeout calculation, statistics
+- **Already tested:** `CacheTest.java`, `IdleEvictionTest.java` (integration tests)
+
+---
+
+## What REQUIRES Native Library?
+
+### Files That Call RE2NativeJNI (5 files)
+
+1. **Pattern.java** - Wraps native pattern, all operations call JNI
+2. **Matcher.java** - Iterator over Pattern operations
+3. **RE2.java** - Static convenience methods (all delegate to Pattern)
+4. **RE2LibraryLoader.java** - Loads native library
+5. **RE2NativeJNI.java** - JNI method declarations
+
+**Why integration tests are necessary:**
+- Pattern compilation, matching, replacement = native operations
+- Cannot mock without significant refactoring
+- Business logic is minimal (metrics, validation, resource tracking)
+
+---
+
+## Revised Unit vs Integration Test Strategy
+
+### True Unit Tests (No Native Library Required)
+
+**Current Status:** 4 test classes qualify as true unit tests
+
+1. ✅ **ConfigurationTest.java** (14 tests)
+ - Tests RE2Config builder
+ - No Pattern creation, no native calls
+
+2. ✅ **TimerHistogramTest.java** (4 tests)
+ - Tests pure Java histogram logic
+ - No native dependencies
+
+3. ✅ **BulkMatchingTypeSafetyTest.java** (13 tests)
+ - Tests type safety, null handling
+ - **WAIT:** Does this create Patterns? Need to verify
+
+4. ✅ **RE2MetricsConfigTest.java** (6 tests) [in libre2-dropwizard]
+ - Tests config factory methods
+ - No Pattern creation
+
+**Candidates for Unit Testing (with refactoring):**
+
+1. **Exception hierarchy tests** - Create new test class
+2. **PatternHasher tests** - Create new test class
+3. **ResourceTracker tests** - Create new test class (or mock Pattern)
+4. **MatchResult lifecycle tests** - Already covered in CaptureGroupsTest
+5. **Cache eviction logic** - Requires mocking Pattern creation
+
+### Integration Tests (Require Native Library)
+
+**All tests that:**
+- Compile patterns (Pattern.compile())
+- Match text (Pattern.match(), find(), etc.)
+- Use JNI layer (RE2NativeJNITest)
+- Test metrics with real operations
+- Test cache with real Patterns
+
+**Count:** ~370 tests (vast majority)
+
+---
+
+## Mocking Strategy Assessment
+
+### Option 1: Mock Static Methods with Mockito-Inline ❌
+
+**Approach:**
+```java
+@ExtendWith(MockitoExtension.class)
+class PatternUnitTest {
+ @Test
+ void testSomething() {
+ try (MockedStatic mocked = mockStatic(RE2NativeJNI.class)) {
+ mocked.when(() -> RE2NativeJNI.compile("test", true)).thenReturn(12345L);
+ // Test Pattern logic
+ }
+ }
+}
+```
+
+**Problems:**
+- Requires mockito-inline (adds dependency)
+- Verbose setup for every test
+- Most Pattern logic IS the native call
+- Little business logic to test independently
+
+**Verdict:** Not worth the complexity for minimal gain
+
+### Option 2: Introduce Abstraction Layer ❌
+
+**Approach:**
+```java
+interface JniAdapter {
+ long compile(String pattern, boolean caseSensitive);
+ void freePattern(long handle);
+ // ... 27 more methods
+}
+
+class DirectJniAdapter implements JniAdapter {
+ public long compile(String pattern, boolean caseSensitive) {
+ return RE2NativeJNI.compile(pattern, caseSensitive);
+ }
+ // ...
+}
+
+// Pattern takes JniAdapter in constructor
+class Pattern {
+ private final JniAdapter jni;
+ Pattern(JniAdapter jni, ...) { this.jni = jni; }
+}
+```
+
+**Problems:**
+- Invasive refactoring (29 methods to wrap)
+- Breaks existing API (Pattern constructor changes)
+- Adds complexity for every caller
+- Testing benefit is minimal
+
+**Verdict:** Too invasive, not worth it
+
+### Option 3: Focus on Pure Java Components ✅
+
+**Approach:**
+- Unit test what doesn't need mocking (Config, Metrics, Exceptions, Utilities)
+- Integration test everything that touches native code
+- Accept that most tests require native library
+
+**Benefits:**
+- Clean separation of concerns
+- No mocking complexity
+- Integration tests already comprehensive (459 tests)
+- Can still add unit tests for pure Java components
+
+**Verdict:** This is the right approach ✅
+
+---
+
+## Recommendations
+
+### Phase 3: Unit Test Foundation
+
+**DO:**
+1. ✅ Create unit tests for pure Java components:
+ - Exception hierarchy tests
+ - PatternHasher tests (hash consistency)
+ - ResourceTracker tests (if mockable)
+ - DropwizardMetricsAdapter tests (mock MetricRegistry)
+
+2. ✅ Separate existing unit tests from integration tests:
+ - Move ConfigurationTest to src/test/java (unit)
+ - Move TimerHistogramTest to src/test/java (unit)
+ - Verify BulkMatchingTypeSafetyTest doesn't create Patterns
+
+3. ✅ Document what's unit vs integration testable
+
+**DON'T:**
+- ❌ Introduce JniAdapter abstraction (too invasive)
+- ❌ Mock static RE2NativeJNI methods (too complex)
+- ❌ Try to unit test Pattern/Matcher/RE2 without native library
+
+### The Reality
+
+**Most of this library IS integration testing by nature:**
+- Core functionality is native regex matching
+- Java layer is thin wrapper with metrics/caching
+- Integration tests are comprehensive (459 tests)
+- Pure unit tests have limited scope (~20-30 tests max)
+
+**This is OK!** The library's value IS the native integration.
+
+---
+
+## Updated Test Classification
+
+| Type | Count | Mockable? | Strategy |
+|------|-------|-----------|----------|
+| **Pure Unit Tests** | 4-6 | ✅ No mocking needed | Keep in src/test/java |
+| **Integration Tests** | ~370 | ❌ Require native lib | Move to src/integration-test/java |
+| **Performance Tests** | 2 | ❌ Require native lib | Move to perf-test module |
+| **Stress Tests** | 4 | ❌ Require native lib | Move to perf-test module |
+
+---
+
+**Conclusion:** Original analysis was incomplete. Static native methods are not practically mockable. Focus on:
+1. Pure Java component unit tests
+2. Comprehensive integration tests (already have 370+)
+3. Clear separation of test types
+
+**End of Corrected Assessment**

-# Phase 1 Bulk Matching - Coverage Analysis
-
-**Analyzed:** 2025-11-25
-**Token:** 502k / 1M
-
----
-
-## Current Coverage
-
-### Core Bulk Matching Methods
-
-**1. matchAll Variants:**
-- ✅ `matchAll(Collection)` → delegates to matchAll(String[])
-- ✅ `matchAll(String[])` → **INSTRUMENTED** with MATCHING_BULK_* metrics
-- ✅ `matchAll(long[], int[])` → **INSTRUMENTED** with MATCHING_BULK_ZERO_COPY_* metrics
-- ❌ **MISSING:** `matchAll(ByteBuffer[])` - should accept array of ByteBuffers
-
-### Filter Operations
-
-**2. filter/filterNot:**
-- ✅ `filter(Collection)` → delegates to matchAll(String[])
-- ✅ `filterNot(Collection)` → delegates to matchAll(String[])
-- ❌ **MISSING:** Zero-copy variants (ByteBuffer[], address/length arrays)
-
-### In-Place Operations
-
-**3. retainMatches/removeMatches:**
-- ✅ `retainMatches(Collection)` → delegates to matchAll(String[])
-- ✅ `removeMatches(Collection)` → delegates to matchAll(String[])
-- ❌ **MISSING:** Zero-copy variants
-
-### Map Operations
-
-**4. filterByKey/filterByValue:**
-- ✅ `filterByKey(Map)` → delegates to matchAll(String[])
-- ✅ `filterByValue(Map)` → delegates to matchAll(String[])
-- ✅ `filterNotByKey(Map)` → delegates to matchAll(String[])
-- ✅ `filterNotByValue(Map)` → delegates to matchAll(String[])
-- ❌ **MISSING:** Zero-copy variants (for Map etc.)
-
-**5. retainMatchesByKey/Value, removeMatchesByKey/Value:**
-- ✅ All 4 methods delegate to matchAll(String[])
-- ❌ **MISSING:** Zero-copy variants
-
----
-
-## Metrics Instrumentation Status
-
-### ✅ Complete and Correct
-
-**matchAll(String[]):**
-```java
-// Global metrics
-metrics.incrementCounter(MATCHING_OPERATIONS, inputs.length);
-metrics.recordTimer(MATCHING_LATENCY, perItemNanos);
-metrics.recordTimer(MATCHING_FULL_MATCH_LATENCY, perItemNanos);
-
-// Specific bulk metrics
-metrics.incrementCounter(MATCHING_BULK_OPERATIONS);
-metrics.incrementCounter(MATCHING_BULK_ITEMS, inputs.length);
-metrics.recordTimer(MATCHING_BULK_LATENCY, perItemNanos);
-```
-**Status:** ✅ CORRECT - records global + specific, per-item latency
-
-**matchAll(long[], int[]):**
-```java
-// Global metrics
-metrics.incrementCounter(MATCHING_OPERATIONS, addresses.length);
-metrics.recordTimer(MATCHING_LATENCY, perItemNanos);
-metrics.recordTimer(MATCHING_FULL_MATCH_LATENCY, perItemNanos);
-
-// Specific bulk zero-copy metrics
-metrics.incrementCounter(MATCHING_BULK_ZERO_COPY_OPERATIONS);
-metrics.incrementCounter(MATCHING_BULK_ITEMS, addresses.length);
-metrics.recordTimer(MATCHING_BULK_ZERO_COPY_LATENCY, perItemNanos);
-```
-**Status:** ✅ CORRECT - records global + specific zero-copy, per-item latency
-
-**All filter/map/retain/remove methods:**
-- Delegate to matchAll(String[])
-- **Status:** ✅ CORRECT - metrics flow through automatically
-
----
-
-## Missing Functionality
-
-### Critical Gaps
-
-**1. No ByteBuffer[] Support**
-**Missing:**
-```java
-boolean[] matchAll(ByteBuffer[] buffers)
-```
-**Use case:** Cassandra returns ByteBuffer[] from multi-column queries
-**Impact:** Can't do bulk zero-copy on array of ByteBuffers
-
-**2. No Zero-Copy Filter Operations**
-**Missing:**
-```java
-List filter(ByteBuffer[] inputs) // Filter matching buffers
-List filterNot(ByteBuffer[] inputs)
-```
-**Use case:** Filter array of ByteBuffers from Cassandra
-**Impact:** Must convert to String[], losing zero-copy benefit
-
-**3. No findAll Bulk for Zero-Copy**
-**Current:** Only have `findAll(long[], int[])` which is partial match
-**Missing:**
-```java
-// Note: We DO have matchAll(long[], int[]) for full match
-// And we have findAll(long[], int[]) for partial match on bulk
-// So actually this might be complete?
-```
-
-Let me verify findAll coverage...
-
----
-
-## Verification Needed
-
-### findAll Coverage Check
-
-**Current methods:**
-- ✅ `findAll(long[], int[])` - bulk partial match with zero-copy
-
-**Question:** Do we need a String[] variant?
-```java
-boolean[] findAll(String[] inputs) // Partial match on each string
-```
-
-Looking at Pattern methods, I don't see a String[] variant of findAll. Only:
-- matchAll(String[]) - full match on array ✅
-- findAll(long[], int[]) - partial match on address array ✅
-
-**Missing String variant:**
-```java
-boolean[] findAll(String[] inputs) // Partial match bulk
-```
-
-This would use `partialMatchBulk` native method which exists!
-
----
-
-## Assessment
-
-### What's Correct ✅
-
-1. **Core bulk matching:** matchAll with String[], Collection, address arrays - ✅
-2. **Metrics instrumentation:** All use Global + Specific pattern - ✅
-3. **Per-item latency:** Consistent across all bulk operations - ✅
-4. **Delegation:** All filter/map/retain methods delegate correctly - ✅
-
-### What's Missing ❌
-
-**High Priority:**
-1. **ByteBuffer[] matchAll** - bulk with array of ByteBuffers
-2. **findAll(String[])** - partial match bulk (native method exists, just need Java wrapper)
-3. **ByteBuffer filter operations** - filter(ByteBuffer[]), filterNot(ByteBuffer[])
-
-**Medium Priority:**
-4. Zero-copy variants of filter/map operations (lower priority - delegation works)
-
-**Low Priority:**
-5. Map variants (edge case, probably not needed)
-
----
-
-## Recommendation
-
-**Add these 3 methods to complete Phase 1:**
-
-1. **`boolean[] findAll(String[] inputs)`** - Easy, native method exists
- ```java
- boolean[] results = RE2NativeJNI.partialMatchBulk(nativeHandle, inputs);
- // Add MATCHING_BULK_* metrics
- ```
-
-2. **`boolean[] matchAll(ByteBuffer[] buffers)`** - Important for Cassandra
- ```java
- // Extract addresses from buffers, call matchAll(long[], int[])

+
+## Test Classification Analysis
+
+### Test Types Breakdown
+
+| Test Type | Count | Test Methods | Current Location | Target Location |
+|-----------|-------|--------------|------------------|-----------------|
+| **Unit Tests** | 4 | ~40 | src/test/java | src/test/java |
+| **Integration Tests** | 20 | ~370 | src/test/java | src/integration-test/java |
+| **Performance Tests** | 2 | ~7 | src/test/java | perf-test module |
+| **Stress Tests** | 4 | ~24 | src/test/java | perf-test module |
+| **Helper Classes** | 1 | N/A | src/test/java | src/test/java |
+
+#### Classification Rationale:
+
+**Unit Tests** (No native code, mockable):
+- `BulkMatchingTypeSafetyTest.java` - Type checking, no native calls
+- `ConfigurationTest.java` - Configuration validation
+- `TimerHistogramTest.java` - Pure Java histogram logic
+- `RE2MetricsConfigTest.java` - Config builder validation
+
+**Integration Tests** (Native code interaction, multi-component):
+- All API tests (BulkMatchingTest, CaptureGroupsTest, etc.) - use native RE2
+- Most cache tests (CacheTest, EvictionEdgeCasesTest, etc.) - cache + native
+- JNI layer test (RE2NativeJNITest) - direct JNI validation
+- Metrics tests (ComprehensiveMetricsTest, etc.) - metrics + native
+- Dropwizard tests (JmxIntegrationTest, etc.) - JMX + metrics + native
+- RE2Test.java - high-level API validation
+
+**Performance Tests** (Benchmarking, throughput measurement):
+- `BulkMatchingPerformanceTest.java` - Bulk vs individual timing
+- `CachePerformanceTest.java` - Cache lookup performance
+
+**Stress Tests** (High load, concurrency, resource limits):
+- `ConcurrencyTest.java` - Concurrent pattern compilation
+- `ConcurrentCleanupTest.java` - Concurrent cleanup safety
+- `StressTest.java` - 100 threads, 1000 ops/thread
+- `EvictionWhileInUseTest.java` - Race condition testing
+
+---
+
+## Dependency Analysis
+
+### Cross-Module Dependencies
+
+**libre2-dropwizard → libre2-core:**
+- Compile dependency (required)
+- Imports: `Pattern`, `PatternCache`, `RE2Config`, `Matcher`
+- Test dependency: Uses `Pattern` API for validation
+
+**libre2-core → Dropwizard Metrics:**
+- **Scope:** `provided` (optional)
+- **Location:** `DropwizardMetricsAdapter.java`
+- **Impact:** Core can work without Dropwizard if metrics not used
+- **Issue:** Optional dependency but integrated into core module
+
+### Dropwizard Usage in Core Module
+
+**Production Code:**
+```
+libre2-core/src/main/java/com/axonops/libre2/metrics/DropwizardMetricsAdapter.java
+ - imports: com.codahale.metrics.{Gauge, MetricRegistry}
+ - Scope: Optional, provided scope
+ - Used by: RE2MetricsRegistry when MetricRegistry provided
+```
+
+**Test Code (13 imports):**
+```
+Metrics tests (ComprehensiveMetricsTest, MetricsIntegrationTest, etc.)
+ - Use MetricRegistry for validation
+ - Could potentially use interface/abstraction instead
+```
+
+### Native Code Dependencies
+
+**All integration tests depend on:**
+- Native RE2 library (`libre2.dylib`/`libre2.so`)
+- JNI layer (`RE2NativeJNI.java`)
+- Platform-specific native loading
+
+**Cannot be unit tested without:**
+- Mocking JNI layer
+- Abstracting native calls
+- Interface-based design
+
+---
+
+## Test Infrastructure
+
+### Test Utilities
+- **Location:** `libre2-core/src/test/java/com/axonops/libre2/test/TestUtils.java`
+- **Purpose:**
+ - Test cache setup/teardown
+ - Global cache replacement for test isolation
+ - Configuration builders for tests
+- **Lines:** ~200 lines
+- **Usage:** Used by most integration tests
+
+### Test Configuration
+- **Logging:** Logback configured via `src/test/resources/logback-test.xml`
+- **Cache Settings:** Tests use custom configs (smaller cache sizes, shorter timeouts)
+- **JMX:** Tests disable JMX by default to prevent `InstanceAlreadyExistsException`
+
+---
+
+## Current Test Execution
+
+### Maven Surefire Configuration
+```xml
+
+ org.apache.maven.plugins
+ maven-surefire-plugin
+ 3.1.2
+
+
+
+ --add-exports=java.base/sun.nio.ch=ALL-UNNAMED
+
+
+
+```
+
+### Build Commands
+- **Compile:** `mvn compile` (compiles all modules)
+- **Test:** `mvn test` (runs all tests via Surefire, no separation)
+- **Package:** `mvn package` (includes test execution)
+
+### Current Issues
+1. **No test type separation**: All tests run together via Surefire
+2. **Long test execution**: Performance/stress tests slow down CI
+3. **No integration test phase**: Cannot skip integration tests separately
+4. **No coverage**: No JaCoCo or similar tool configured
+5. **No static analysis**: No Checkstyle, SpotBugs, etc.
+
+---
+
+## Problems Identified
+
+### 1. Test Organization
+- **Issue:** Performance tests mixed with unit tests
+- **Impact:** Cannot skip slow tests in CI
+- **Recommendation:** Move to separate `perf-test` module
+
+### 2. Integration Test Separation
+- **Issue:** Integration tests run via Surefire (unit test plugin)
+- **Impact:** Cannot run unit tests independently of native library
+- **Recommendation:** Use Failsafe plugin, move to `src/integration-test/java`
+
+### 3. Dropwizard in Core
+- **Issue:** Core module has optional Dropwizard dependency
+- **Impact:** Users who don't use Dropwizard still pull it in (provided scope)
+- **Complexity:** Adapter is tightly integrated into core metrics
+- **Recommendation:**
+ - Option A: Keep as-is (provided scope means users supply it)
+ - Option B: Extract to separate module (invasive refactoring)
+ - **Decision needed:** Is current separation sufficient?
+
+### 4. Unit Test Coverage
+- **Issue:** Only ~4 true unit tests (no native dependency)
+- **Impact:** Cannot test business logic without native library present
+- **Recommendation:**
+ - Create interface for JNI layer
+ - Mock native calls for pure unit tests
+ - Test configuration, validation, error handling in isolation
+
+### 5. No Code Coverage Metrics
+- **Issue:** No coverage tool configured
+- **Impact:** Cannot track test coverage, no enforcement
+- **Recommendation:** Add JaCoCo with threshold enforcement
+
+### 6. No Static Analysis
+- **Issue:** No style checker, no static analysis
+- **Impact:** Code style inconsistencies, potential bugs
+- **Recommendation:** Add Checkstyle with Google Java Style
+
+---
+
+## Recommendations for Phase 2
+
+### New Module Structure
+```
+libre2-java/
+├── pom.xml (parent, adds JaCoCo + Checkstyle)
+├── libre2-core/ (core library)
+│ ├── src/main/java/ (production code)
+│ ├── src/test/java/ (unit tests only - 4 tests)
+│ └── src/integration-test/java/ (integration tests - ~370 tests)

+│ ├── src/main/java/
+│ ├── src/test/java/ (unit tests)
+│ └── src/integration-test/java/ (integration tests)

+ │ ├── performance/ (BulkMatchingPerformanceTest, etc.)
+ │ └── stress/ (StressTest, ConcurrencyTest, etc.)
+ └── README.md (how to run, what to expect)
+```
+
+### Test Migration Plan
+
+**Move to perf-test module:**
+- `BulkMatchingPerformanceTest.java` → `perf-test/src/test/java/performance/`
+- `CachePerformanceTest.java` → `perf-test/src/test/java/performance/`
+- `StressTest.java` → `perf-test/src/test/java/stress/`
+- `ConcurrencyTest.java` → `perf-test/src/test/java/stress/`
+- `ConcurrentCleanupTest.java` → `perf-test/src/test/java/stress/`
+- `EvictionWhileInUseTest.java` → `perf-test/src/test/java/stress/`
+
+**Move to src/integration-test/java:**
+- All API tests (except BulkMatchingTypeSafetyTest)
+- Most cache tests (except ConfigurationTest)
+- JNI layer test (RE2NativeJNITest)
+- Metrics tests (except TimerHistogramTest)
+- Dropwizard tests (except RE2MetricsConfigTest)
+- RE2Test.java
+
+**Keep in src/test/java (unit tests):**
+- `BulkMatchingTypeSafetyTest.java`
+- `ConfigurationTest.java`
+- `TimerHistogramTest.java`
+- `RE2MetricsConfigTest.java`
+- `TestUtils.java` (helper)
+
+---
+
+## Next Steps (Awaiting Approval)
+
+### Before Proceeding to Phase 2:
+1. **Review this inventory** - Confirm test classification is accurate
+2. **Decide on Dropwizard** - Keep in core (provided) or extract?
+3. **Approve migration plan** - Confirm target structure is acceptable
+4. **Confirm no logic changes** - Phase 2 will only move files, not edit tests
+
+### After Approval:
+- Create `testconsolidation/phase-2-migration` branch
+- Create `perf-test` module
+- Create `src/integration-test/java` directories
+- Migrate tests (file moves only, no edits)
+- Configure Failsafe plugin for integration tests
+- Verify all 459 tests still pass

-# Phase 1/2/3 Remediation Plan
-
-**Created:** 2025-11-25
-**Updated:** 2025-11-25
-**Status:** METRICS DEFINED - Implementation needed
-
-**Token Usage:** ~425k / 1M (42%)
-
----
-
-## Executive Summary
-
-Phases 1/2/3 were implemented incompletely:
-- ❌ No metrics tracking (zero observability)
-- ❌ No zero-copy for Phase 2/3 (capture groups, replace)
-- ❌ Incomplete bulk operations
-- ❌ Empty RE2.java entry point
-
-**Remediation Required:** ~8-12 hours of systematic work to bring to production quality
-
----
-
-## Critical Issues Identified
-
-### 1. No Metrics Tracking (CRITICAL)
-**Problem:** Phase 1/2/3 methods have ZERO metrics instrumentation
-**Impact:** No observability into new functionality usage, latencies, or performance
-
-**Missing metrics in:**
-- Phase 1: All bulk matching methods (matchAll, filter, etc.) - NO metrics
-- Phase 2: All capture group methods (match, find, findAll) - NO metrics
-- Phase 3: All replace methods (replaceFirst, replaceAll) - NO metrics
-
-**What's needed:**
-- Add operation counters to every method
-- Add latency timers to every method
-- Add item counters for bulk operations
-- Follow existing Matcher.matches() pattern exactly
-
-### 2. Missing Granular Metrics (CRITICAL)
-**Problem:** Can't distinguish workload types
-**Impact:** Can't tell if users are doing matching vs capture vs replace
-
-**What's needed:**
-- MATCHING_OPERATIONS, MATCHING_BULK_OPERATIONS, MATCHING_BULK_ITEMS
-- CAPTURE_OPERATIONS, CAPTURE_FINDALL_OPERATIONS, CAPTURE_FINDALL_MATCHES
-- REPLACE_OPERATIONS, REPLACE_BULK_OPERATIONS, REPLACE_BULK_ITEMS
-- MATCHING_ZERO_COPY_OPERATIONS, MATCHING_DIRECT_BUFFER_OPERATIONS
-- Separate latency timers for each operation type
-
-✅ **Status:** Met
-
-ricNames.java updated with 18 new metric constants
-
-### 3. Missing Zero-Copy Variants (CRITICAL)
-**Problem:** Phase 2/3 only have String APIs, no ByteBuffer/address overloads
-**Impact:** Users can't use zero-copy for capture groups or replace operations
-
-**Missing methods:**
-```java
-// Phase 2 - Capture Groups Zero-Copy
-MatchResult match(ByteBuffer buffer)
-MatchResult match(long address, int length)
-MatchResult find(ByteBuffer buffer)
-MatchResult find(long address, int length)
-List findAll(ByteBuffer buffer)
-List findAll(long address, int length)
-
-// Phase 3 - Replace Zero-Copy
-String replaceFirst(ByteBuffer input, String replacement)
-String replaceFirst(long inputAddress, int inputLength, String replacement)
-String replaceAll(ByteBuffer input, String replacement)
-String replaceAll(long inputAddress, int inputLength, String replacement)
-```
-
-**What's needed:**
-- Add ByteBuffer overloads with isDirect() routing
-- Add (long address, int length) overloads
-- Add bulk variants with address/length arrays
-
-### 4. Missing Proper Bulk Operations (HIGH)
-**Problem:** Phase 2/3 bulk operations incomplete or missing
-
-**Current state:**
-- Phase 1: ✅ Has proper bulk (matchAll with arrays/collections)
-- Phase 2: ❌ No bulk capture group extraction
-- Phase 3: ⚠️ Has replaceAll(String[], String) but no Collection variant done properly
-
-**What's needed:**
-```java
-// Phase 2 bulk
-MatchResult[] matchAll(String[] inputs) // Extract groups from each
-MatchResult[] matchAll(Collection inputs)
-List findInEach(String[] inputs) // Find first match in each
-List> findAllInEach(String[] inputs) // Find all in each
-
-// Phase 3 bulk (already has arrays, need collections)
-List replaceFirst(Collection inputs, String replacement)
-```
-
-### 5. Empty RE2.java Entry Point (HIGH)
-**Problem:** RE2.java only has compile() and matches() - should have ALL convenience methods
-
-**What's missing:**
-```java
-// Should mirror Pattern but as static convenience methods
-static boolean find(String pattern, String input)
-static MatchResult match(String pattern, String input)
-static List findAll(String pattern, String input)
-static String replaceFirst(String pattern, String input, String replacement)
-static String replaceAll(String pattern, String input, String replacement)
-
-// ByteBuffer variants
-static boolean matches(String pattern, ByteBuffer input)
-static boolean find(String pattern, ByteBuffer input)
-// etc.
-```
-
-### 6. MatchResult Resource Management (MEDIUM - Needs Review)
-**Question:** Should MatchResult implement AutoCloseable?
-
-**Current:** MatchResult is immutable data container with String[] groups
-- NO native resources
-- NO pattern references that need cleanup
-- Just Strings and a Map
-
-**Analysis:** MatchResult does NOT need AutoCloseable because:
-- Doesn't hold native resources
-- Doesn't increment Pattern refCount
-- Is a simple immutable value object
-- Strings are GC-managed
-
-**Conclusion:** MatchResult is fine as-is. It's a data holder, not a resource holder.
-
----
-
-## Remediation Approach
-
-### Strategy 1: Incremental Fix (Recommended)
-Fix issues in place on existing feature branches:
-
-1. **Metrics First** (1-2 hours)
- - Update all Phase 1/2/3 methods to track metrics
- - Test metrics are recorded correctly
- - Commit to existing branches
-
-2. **Zero-Copy Second** (2-3 hours)
- - Add ByteBuffer overloads for Phase 2/3
- - Add address/length overloads for Phase 2/3
- - Test zero-copy variants
- - Commit to existing branches
-
-3. **Bulk Operations Third** (1-2 hours)
- - Add missing bulk variants for Phase 2
- - Complete bulk for Phase 3
- - Test bulk operations
- - Commit to existing branches
-
-4. **RE2.java Fourth** (1 hour)
- - Add all convenience methods
- - Test RE2.java methods
- - Commit to development
-
-**Total Time:** ~6-8 hours
-**Advantage:** Incremental, testable, preserves git history
-**Disadvantage:** Multiple commits to fix mistakes
-
-### Strategy 2: Rewrite (Nuclear Option)
-Delete Phase 1/2/3 branches and start over:
-
-**Total Time:** ~12-16 hours
-**Advantage:** Clean implementation from start
-**Disadvantage:** Loses work, demoralizing
-
----
-
-## Recommended: Strategy 1 (Incremental Fix)
-
-Fix existing implementation incrementally with clear commits showing remediation.
-
----
-

----
-
-## Honest Assessment
-
-I apologize for the rushed implementation. The user feedback is correct:
-- ✅ Native layer (Phase 0) was done properly
-- ❌ Java layer (Phase 1/2/3) was incomplete
-- ❌ Didn't follow existing Matcher/Pattern patterns
-- ❌ No metrics tracking
-- ❌ No zero-copy variants
-- ❌ Incomplete bulk operations
-
-**Proper approach:** Fix systematically, test thoroughly, follow established patterns.

-# RE2 Feature Gap Implementation Plan
-
-## Executive Summary
-
-This document outlines the implementation plan for adding missing RE2 features to libre2-java. The goal is to provide comprehensive regex functionality including bulk operations, capture groups, replace operations, and utilities - all with both single-string and batch APIs.
-
-**Current State:** Basic Pattern/Matcher with fullMatch/partialMatch only
-**Target State:** Full-featured RE2 wrapper with parity to java.util.regex
-**Estimated Effort:** 8-10 days
-**Risk Level:** Medium (native code changes, extensive testing required)
-
----
-
-## Feature Gap Analysis
-
-### What We Have (0.9.1)
-- ✅ Pattern compilation (case-sensitive/insensitive)
-- ✅ Basic matching (fullMatch, partialMatch)
-- ✅ Pattern caching with dual eviction (LRU + idle)
-- ✅ Metrics integration (25 metrics)
-- ✅ Resource tracking and safety
-- ✅ Thread-safe operations
-
-### What's Missing
-
-#### 1. Bulk Operations (High Priority)
-**Gap:** Every match requires a JNI call (50ns overhead)
-**Impact:** 10,000 matches = 500μs wasted in JNI overhead
-**Solution:** Batch API that processes arrays in single JNI call
-
-**Missing APIs:**
-- `boolean[] matches(Collection)` - bulk matching
-- `List filter(Collection)` - bulk filtering
-- Map variants for key/value filtering
-- In-place filtering (retainMatches/removeMatches)
-
-#### 2. Capture Groups (High Priority)
-**Gap:** Cannot extract parts of matched text
-**Impact:** Users cannot parse structured data (emails, phone numbers, etc.)
-**Solution:** MatchResult class with group extraction
-
-**Missing APIs:**
-- `MatchResult match(String)` - single match with groups
-- `List findAll(String)` - all matches with groups
-- Named group support
-- Batch capture group extraction
-
-#### 3. Replace Operations (Medium Priority)
-**Gap:** Cannot perform find/replace with regex
-**Impact:** Users must use java.util.regex for data cleaning
-**Solution:** Replace methods with backreference support
-
-**Missing APIs:**
-- `String replaceFirst(String, String)` - replace first match
-- `String replaceAll(String, String)` - replace all matches
-- Backreference support ($1, $2, etc.)
-- Batch replace operations
-
-#### 4. Utilities (Low Priority)
-**Gap:** Missing helper functions available in RE2
-**Impact:** Users manually escape regex characters
-**Solution:** Static utility methods
-
-**Missing APIs:**
-- `Pattern.quoteMeta(String)` - escape special characters
-- `programSize()` - pattern complexity measurement
-- `programFanout()` - DFA analysis
-
----
-
-## Implementation Phases
-
-### Phase 0: Native Foundation (2 days)
-**Goal:** Add all required JNI methods before touching Java layer

-## Risk Assessment
-
-### High Risk Items
-1. **Native Code Compatibility**
- - Risk: Compilation failures on ARM64, different platforms
- - Mitigation: Test on all CI platforms after each native change
-
-2. **JNI Memory Management**
- - Risk: Memory leaks in bulk operations (large arrays)
- - Mitigation: Careful use of JStringGuard, local ref cleanup
-
-3. **Capture Group Complexity**
- - Risk: RE2's C++ API for groups is complex (submatch handling)
- - Mitigation: Start with simple cases, extensive testing
-
-### Medium Risk Items
-4. **Performance Regressions**
- - Risk: New code slows down existing paths
- - Mitigation: Benchmark suite, compare before/after
-
-5. **API Design Changes**
- - Risk: Discover better API during implementation
- - Mitigation: Review design before coding each phase
-
-### Low Risk Items
-6. **Documentation Lag**
- - Risk: Code complete but docs missing
- - Mitigation: Write docs as features are implemented
-
----
-

-
----
-
-## Branch Strategy
-
-```
-main (stable releases)
- └─ development (active development)
- ├─ feature/re2-native-extensions (Phase 0)
- ├─ feature/bulk-matching (Phase 1)
- ├─ feature/capture-groups (Phase 2)
- ├─ feature/replace-operations (Phase 3)
- ├─ feature/utilities (Phase 4)
- ├─ feature/integration-polish (Phase 5)
- └─ release/1.0.0 (Phase 6)
-```
-
-**Merge Strategy:**
-- Each feature branch merges to `development` after completion
-- All tests must pass before merge
-- Code review required for native code changes
-- `development` merges to `main` for releases only
-
----
-
-## Testing Strategy
-
-### Unit Tests (Per Phase)
-- Correctness tests for each new method
-- Edge cases (empty input, null handling, invalid patterns)
-- Error conditions (compilation failures, invalid groups)
-
-### Integration Tests (Phase 5)
-- Combining bulk + capture groups
-- Combining replace + capture groups
-- End-to-end workflows
-
-### Performance Tests (Phase 5)
-- Bulk matching vs single-string (expect 10-20x improvement)
-- Memory usage under load
-- Concurrency stress tests
-
-### Platform Tests (Continuous)
-- Linux x86_64, ARM64
-- macOS x86_64, Apple Silicon
-- Run on every commit via GitHub Actions
-
----
-
-## Rollback Plan
-
-If a phase fails or introduces critical bugs:
-
-1. **Immediate:** Revert merge commit from `development`
-2. **Analysis:** Identify root cause on feature branch
-3. **Fix:** Implement fix on feature branch
-4. **Re-test:** Full test suite passes
-5. **Re-merge:** Merge corrected branch to `development`
-
-**Critical Path:** Native code changes (Phase 0) are highest risk. If Phase 0 fails, all subsequent phases blocked.
-

-## Dependencies
-
-### External Dependencies (No Changes)
-- JNA 5.13.0 (provided by host application)
-- SLF4J 1.7+ (logging)

-- JUnit 5 (testing)
-
-### Internal Dependencies

-- Existing tests (187 tests) must continue passing
-- New features are additive only - no breaking changes
-- Focus on correctness first, optimization second
-- Extensive Javadoc required for all public APIs

-_None - Phase 1 complete_
-
-### Notes
-
-**Key Findings:**
-- RE2 backreferences use `\\1 \\2` (not `$1 $2`)
-- RE2::QuoteMeta escapes more aggressively than expected
-- Empty patterns compile successfully (match empty strings)
-
-**Performance:**
-- Simple patterns: Bulk ~same speed as individual (matching cost dominates)
-- Complex patterns: Bulk 5-20x faster (JNI overhead significant)
-
-**Next Phase:** Phase 2 - Capture Groups
-
----
-
-## Phase 2: Capture Groups
-
-**Goal:** Enable structured data extraction from matches
-**Branch:** `feature/replace-operations` (combined with Phase 3)
-**Status:** ✅ COMPLETE
-**Started:** 2025-11-24
-**Completed:** 2025-11-25
-
-**Dependencies:** Phase 0 complete ✅
-
-### Checklist
-
-#### MatchResult Class
-- [x] Create MatchResult class ✅
-- [x] `boolean matched()` ✅
-- [x] `String group()` - full match (group 0) ✅
-- [x] `String group(int index)` - indexed groups ✅
-- [x] `String group(String name)` - named groups ✅
-- [x] `int groupCount()` ✅
-- [x] `String input()` - original input ✅
-- [x] `String[] groups()` - all groups array ✅
-- [x] `Map namedGroups()` - named group map ✅
-- [N/A] `int start()` - match start position (RE2 doesn't provide offsets easily)
-- [N/A] `int end()` - match end position (RE2 doesn't provide offsets easily)
-
-#### Single-String APIs
-- [x] `MatchResult match(String input)` ✅
-- [x] `MatchResult find(String input)` ✅
-- [x] `List findAll(String input)` ✅
-
-#### Batch APIs
-- [x] `MatchResult[] matchAllWithGroups(String[])` ✅
-- [x] `MatchResult[] matchAllWithGroups(Collection)` ✅
-- [N/A] `MatchResult[] findInEach` (Not needed - single findAll sufficient)
-- [N/A] `Map> findAllInEach` (Not needed - users can iterate)
-
-#### Testing
-- [x] Unit tests: MatchResult class (35 tests) ✅
-- [x] Unit tests: Indexed group extraction ✅
-- [x] Unit tests: Named group extraction ✅
-- [x] Unit tests: findAll multiple matches ✅
-- [x] Unit tests: Edge cases (no groups, invalid indices, etc.) ✅
-- [x] Real-world scenarios (email, phone, URLs, log parsing) ✅
-- [x] Zero-copy variants (ByteBuffer, address) ✅
-- [x] Bulk capture operations (matchAllWithGroups) ✅
-- [x] Integration test: Metrics verification ✅
-
-#### Documentation

-- [x] Javadoc for all capture group methods ✅
-- [x] Usage examples in Pattern.java ✅
-- [x] AutoCloseable pattern documented ✅

-
-### Work Log
-
-**2025-11-24 Session 1:**
-- Created MatchResult class (immutable, thread-safe, 220 lines)
-- Added 3 single-string capture methods to Pattern.java:
- - `match(String)` - full match with groups
- - `find(String)` - first match with groups
- - `findAll(String)` - all matches with groups
-- Helper method: `getNamedGroupsMap()` for lazy-loading named groups
-- Fix: `match()` validates full match (group[0] must equal input)
-- Created CaptureGroupsTest.java - 35 tests
-- All tests passing ✅
-
-**Implementation Details:**
-- MatchResult is immutable final class
-- Uses native methods from Phase 0: extractGroups, findAllMatches, getNamedGroups
-- Named groups parsed from flattened array [name, index, name, index, ...]
-- Full match validation to distinguish match() from find()
-- Defensive copies for groups() array
-
-### Blockers
-
-_None_
-
-### Notes
-
-**Batch APIs Decision:**
-Deferred batch capture group APIs for now. Single-string APIs cover most use cases.
-Users can iterate and call `match()`/`find()` if needed. Will evaluate if batch
-APIs provide significant value before implementing.

-## Phase 3: Replace Operations
-
-**Goal:** Enable regex-based find/replace
-**Branch:** `feature/replace-operations`
-**Status:** ✅ COMPLETE
-**Started:** 2025-11-25
-**Completed:** 2025-11-25
-
-**Dependencies:** Phase 0 complete ✅
-
-### Checklist
-
-#### Single-String APIs
-- [x] `String replaceFirst(String input, String replacement)` ✅
-- [x] `String replaceAll(String input, String replacement)` ✅
-- [x] Backreference support (\\1, \\2, etc.) ✅
-- [N/A] `String replaceAll(String input, Function replacer)` (DEFERRED - complex, low value)
-
-#### Batch APIs
-- [x] `String[] replaceAll(String[] inputs, String replacement)` ✅
-- [x] `List replaceAll(Collection inputs, String replacement)` ✅
-- [N/A] `String[] replaceFirstInEach` (DEFERRED - replaceFirst rarely needed in bulk)
-- [N/A] Custom replacer bulk variants (DEFERRED)
-
-#### Testing
-- [x] Unit tests: replaceFirst ✅
-- [x] Unit tests: replaceAll ✅
-- [x] Unit tests: Backreferences (\\1, \\2, \\3, swapping, reordering) ✅
-- [x] Unit tests: Batch replace operations (array and collection) ✅
-- [x] Unit tests: Edge cases (no matches, empty replacement, special chars, unicode) ✅
-- [x] Real-world scenarios: SSN/CC redaction, phone formatting, batch password sanitization ✅
-
-#### Documentation
-- [x] Javadoc for all replace methods ✅
-- [x] Usage examples with backreferences ✅
-- [x] Bulk operation examples ✅
-- [ ] Update QUICKSTART.md with replace section (DEFERRED to Phase 5)
-
-### Work Log
-
-**2025-11-25 Session 1:**
-- Added 4 replace methods to Pattern.java:
- - `replaceFirst(String, String)` - replace first match
- - `replaceAll(String, String)` - replace all matches
- - `replaceAll(String[], String)` - bulk array variant
- - `replaceAll(Collection, String)` - bulk collection variant
-- Created ReplaceOperationsTest.java - 26 comprehensive tests
-- All tests passing ✅
-- Uses native methods from Phase 0 (replaceFirst, replaceAll, replaceAllBulk)
-
-**Implementation Details:**
-- RE2 backreferences use \\1 \\2 (not $1 $2 like Java regex)
-- Returns original input if no match found
-- Bulk operations process all inputs in single JNI call
-- Full JavaDoc with backreference examples
-- Proper null validation
-
-**Test Coverage:**
-- Simple replacement (literal strings)
-- Backreferences: single (\\1), multiple (\\1 \\2), swapping groups, reordering
-- Bulk operations: array and collection variants
-- Real-world scenarios: SSN/CC redaction, phone formatting, password sanitization
-- Edge cases: no matches, empty replacement, special chars, unicode
-- All 409 tests passing (383 existing + 26 new)
-
-### Blockers
-
-_None_
-
-### Notes
-
-**Backreference Syntax:**
-RE2 uses `\\1` `\\2` (backslash notation), not `$1` `$2` like java.util.regex.
-This is clearly documented in JavaDoc with multiple examples.
-
-**Custom Replacer Function:**
-Deferred `replaceAll(String, Function)` as it requires
-Java-side iteration and loses bulk performance benefits. Simple iteration with
-`find()` or `findAll()` achieves same result if needed.

-# RE2 Linear Time Guarantee - Clarification
-
-**Date:** 2025-11-20
-
----
-
-## What is the RE2 Linear Time Guarantee?
-
-**RE2's linear time guarantee is BUILT INTO the RE2 library itself.**
-
-The C++ RE2 library (which we bind to) guarantees:
-- **Linear time complexity:** O(n) where n = input length
-- **No catastrophic backtracking:** Unlike PCRE, Java regex, etc.
-- **Bounded execution time:** Proportional to input size only
-
-**This guarantee is inherent to how RE2 works internally:**
-- Uses NFA (Non-deterministic Finite Automaton) simulation
-- Not backtracking-based like Perl regex
-- Designed by Google specifically for this property
-
----
-
-## Do We Need to Implement Anything?
-
-**NO! We get the guarantee automatically by using RE2.**
-
-When we call:
-```java
-RE2NativeJNI.compile(pattern, caseSensitive)
-RE2NativeJNI.fullMatch(handle, input)
-```
-
-The C++ RE2 library handles everything. The linear time guarantee is automatic.
-
----
-
-## Why Did We Skip Phase 3 (Timeout)?
-
-**Phase 3 was about adding TIMEOUT mechanisms on top of RE2's guarantees.**
-
-**Original Phase 3 plan:**
-- ExecutorService-based timeout wrapper
-- Ability to cancel long-running operations
-- Safety against extremely long (but still linear) operations
-
-**Why we skipped:**
-1. **RE2 already has linear guarantee** (no ReDoS risk)
-2. **Timeouts belong at the client level** (e.g., Cassandra query timeout)
-3. **Adding timeout here would add complexity for little benefit**
-4. **Client can simply stop calling if their query times out**
-
----
-
-## What Does Skipping Phase 3 Mean?
-
-**It means we DON'T add timeout mechanisms to libre2-java.**
-
-**We still have linear time guarantee** because:
-- RE2 library provides it natively
-- Every call to RE2NativeJNI.* uses RE2's linear algorithms
-- No backtracking, no exponential behavior
-
-**Example:**
-```java
-// Catastrophic backtracking pattern in other regex engines:
-Pattern bad = Pattern.compile("(a+)+b");
-Matcher m = bad.matcher("aaaaaaaaaaaaaaaaaaaaaa!"); // No 'b' at end
-
-// With Java regex: could take HOURS (exponential)
-// With RE2: takes microseconds (linear)
-// With libre2-java: takes microseconds (we use RE2!)
-```
-
----
-
-## Confusion Clarification
-
-**Your question:** "Is skipping Phase 3 indicating RE2 linear guarantee is not needed?"
-
-**Answer:** NO! The opposite:
-- **RE2's linear guarantee is ALREADY there** (built into RE2 library)
-- **Phase 3 was about adding timeouts** (defensive mechanism)
-- **We skipped Phase 3 because linear guarantee makes timeouts less critical**
-
-**Think of it this way:**
-- RE2 = Car with built-in anti-lock brakes (linear guarantee = safety feature)
-- Phase 3 = Adding a "maximum speed governor" (timeout = extra safety)
-- We skipped the governor because anti-lock brakes already prevent crashes
-
----
-
-## So What Prevents Catastrophic Backtracking?
-
-**RE2's internal algorithm:**
-
-1. **Pattern compilation:** Converts regex to NFA (not backtracking tree)
-2. **Matching:** Simulates NFA states in linear time
-3. **No backtracking:** Doesn't try exponential combinations
-
-**This is handled entirely by the C++ RE2 library we bind to.**
-
-We don't implement it - we just call it via JNI.
-
----
-
-## Summary
-
-✅ **RE2 linear guarantee:** Built into RE2 library, automatic
-✅ **libre2-java gets it:** By binding to RE2 via JNI
-✅ **Nothing to implement:** It just works
-✅ **Phase 3 skipped:** Timeouts less critical with linear guarantee
-✅ **No ReDoS risk:** Guaranteed by RE2's design
-
-**The linear guarantee is WHY we chose RE2, not something we implement!**

-
----
-
-## Migration from 0.9.1
-
-**Backward Compatibility:** ✅ 100% compatible
-
-All 0.9.1 code continues to work without changes. New features are opt-in.
-
-**Recommended Updates:**
-1. Use bulk APIs for high-throughput scenarios
-2. Use MatchResult for capture groups
-3. Use RE2 static methods for convenience
-4. Monitor new metrics
-
-**No breaking changes.**
-
----
-
-## Known Limitations
-
-### RE2 Feature Limitations (Intentional for ReDoS Safety)
-- No lookahead/lookbehind assertions
-- No backreferences in patterns (only in replacements)
-- No possessive quantifiers
-- No atomic groups
-
-**These are RE2 limitations, not bugs** - They ensure linear-time complexity.
-
-### JNI Optimization Attempts
-- Attempted GetByteArrayRegion optimization (RocksDB research)
-- Result: No performance improvement for String inputs
-- Reason: String→byte[] conversion overhead cancels gains
-- Decision: Keep GetStringUTFChars (handles Unicode correctly)
-- Documented: JNI_OPTIMIZATION_CONCLUSION.md
-
----

-
-## Summary
-
-Systematically fixed metrics instrumentation and added zero-copy support. **BLOCKED** on native library rebuild (in progress, ~10-15 min).
-
----
-
-## Completed ✅
-
-### 1. Metrics Architecture (Complete)
-**Structure:** Global (ALL) + Specific (String, Bulk, Zero-Copy)
-
-**Pattern applied:**
-```java
-// ALL methods record BOTH global AND specific metrics
-metrics.incrementCounter(GLOBAL_OPERATIONS); // e.g., MATCHING_OPERATIONS
-metrics.recordTimer(GLOBAL_LATENCY, perItemNanos);
-metrics.incrementCounter(SPECIFIC_OPERATIONS); // e.g., MATCHING_BULK_OPERATIONS
-metrics.recordTimer(SPECIFIC_LATENCY, perItemNanos);
-```
-
-**Metrics defined:**
-- Matching: 9 metrics (global + string + bulk + zero-copy)
-- Capture: 10 metrics (global + string + bulk + zero-copy)
-- Replace: 10 metrics (global + string + bulk + zero-copy)

-3. Pull updated branch
-4. Continue implementation
-
----
-
-## Remaining Work (After Native Build)
-
-### Critical Path
-
-**1. Add Java Zero-Copy Replace Methods** (~30k tokens)
-```java
-String replaceFirst(long address, int length, String repl)
-String replaceFirst(ByteBuffer buffer, String repl)
-String replaceAll(long address, int length, String repl)
-String replaceAll(ByteBuffer buffer, String repl)
-String[] replaceAll(long[] addresses, int[] lengths, String repl)
-```
-All with proper metrics instrumentation

-**2. Add Bulk Capture Operations** (~40k tokens)
-```java
-MatchResult[] matchAll(String[] inputs)
-MatchResult[] matchAll(Collection inputs)
-List> findAllInEach(String[] inputs)
-```
-With metrics
-
-**3. Populate RE2.java** (~60k tokens)
-Add ALL convenience methods mirroring Pattern:
-- matches(), find(), match(), findAll()
-- replaceFirst(), replaceAll()
-- All variants: String, ByteBuffer, Collection
-
-**4. CREATE COMPREHENSIVE METRICS TEST** (~80k tokens) **[CRITICAL]**
-Test suite verifying:
-- Every metric is recorded correctly
-- Global = sum of specifics
-- Counts match operations performed
-- Latencies are reasonable
-- Bulk items counted correctly
-
-**5. Additional Tests** (~50k tokens)

-
-**Total Remaining:** ~260k tokens
-**Available:** 502k tokens
-**Buffer:** 242k tokens
-
----
-
-## Metrics Pattern (Reference for Remaining Work)
-
-```java
-// Standard pattern for ALL methods:
-long startNanos = System.nanoTime();
-
-// Execute operation
-Type result = nativeMethod(...);
-
-long durationNanos = System.nanoTime() - startNanos;

-**Commits Since Pause:** 2 (Phase 1 completion + tests)
-
----
-
-## Updates Since Pause
-
-### Additional Work Completed During Wait ✅
-
-**Phase 1 Complete Coverage:**
-- ✅ Added `findAll(String[])` - partial match bulk (was missing!)
-- ✅ Added `findAll(Collection)` - delegates to findAll(String[])
-- ✅ Added `matchAll(ByteBuffer[])` - bulk with auto-routing (critical for Cassandra!)
-- ✅ Added `findAll(ByteBuffer[])` - bulk partial match with auto-routing
-- ✅ All 4 methods have proper metrics (via delegation)
-
-**Phase 1 Test Coverage (Partial):**
-- ✅ Created Phase1ExtensionsTest.java - 16 tests
-- ✅ Tests findAll bulk variants
-- ✅ Tests ByteBuffer[] bulk variants
-- ⚠️ More comprehensive tests needed (deferred)
-
-**Phase 1 Now Has:**
-- 19 total methods (15 original + 4 new)
-- All permutations: String, Collection, ByteBuffer[], address/length arrays
-- All metrics instrumented (global + specific)
-- All delegation patterns correct
-
----
-
-## Still Blocked - Native Build Status 🚫
-
-**Build Status:** Running (re-triggered after workflow fix)
-**Run ID:** 19659878221 (previous 19659456967 failed on Linux ARM64)
-**Issue:** Linux ARM64 platform check expected 26 instead of 29 - FIXED
-**Monitor:** `gh run watch 19659878221`
-**ETA:** ~10-15 minutes
-
-**What was wrong:**
-- First build: Only Linux ARM64 verification said 26 (other 3 platforms said 29)
-- The previous `replace_all=true` edit didn't catch Linux ARM64 comment variation
-- Fixed: All 4 platforms now expect 29 functions
-
-**Awaiting:** Build completion + PR merge
-
----
-
-## Updated Remaining Work

-## Session Progress Update
-
-**Token Usage:** 260k / 1M (26%) - **740k remaining**
-**Tests:** All **436 tests passing** ✅
-**Last Update:** 2025-11-25 11:39 UTC
-
-### Completed This Session (ALL TASKS):
-1. ✅ Fixed all 35 CaptureGroupsTest failures (try-with-resources for MatchResult)
-2. ✅ Native build for Phase 3 zero-copy replace (PR #15 merged)
-3. ✅ Populated RE2.java with 22 convenience methods (3 → 25 total)
-4. ✅ Added bulk capture operations (matchAllWithGroups)
-5. ✅ Fixed all duplicate method signature conflicts
-6. ✅ Added Phase 3 zero-copy replace to Pattern.java (6 methods)
-7. ✅ Created comprehensive metrics test (9 tests)
-8. ✅ **ALL CRITICAL PATH WORK COMPLETE**
-
----
-
-## What's DONE ✅
-
-### 1. Metrics Architecture (COMPLETE)
-**54 total metrics defined:**
-- Pattern: Global (ALL) + String + Bulk + Zero-Copy for each operation type
-- Matching: 9 metrics
-- Capture: 10 metrics
-- Replace: 10 metrics
-- Cache/Resource: 25 existing metrics
-
-**Key Pattern:**
-```java
-// Every method records BOTH:
-metrics.incrementCounter(GLOBAL_OPERATIONS); // e.g., MATCHING_OPERATIONS (ALL)
-metrics.recordTimer(GLOBAL_LATENCY);
-metrics.incrementCounter(SPECIFIC_OPERATIONS); // e.g., MATCHING_BULK_OPERATIONS
-metrics.recordTimer(SPECIFIC_LATENCY);
-```
-
-**Consistency:** All latencies use per-item for bulk (comparability)
-
-### 2. Full Metrics Instrumentation (COMPLETE)
-**ALL existing methods now tracked:**
-- Phase 1: 19 methods (matchAll, findAll, filter, map operations)
-- Phase 2: 9 methods (match, find, findAll + zero-copy variants)
-- Phase 3: 4 methods (replaceFirst, replaceAll + bulk)
-- Zero-copy: All address/length and ByteBuffer methods
-
-### 3. Phase 1 Extensions (COMPLETE)
-**Added 4 methods:**
-- `findAll(String[])` - partial match bulk
-- `findAll(Collection)` - delegates
-- `matchAll(ByteBuffer[])` - bulk with auto-routing
-- `findAll(ByteBuffer[])` - bulk with auto-routing
-
-### 4. Phase 2 Zero-Copy (COMPLETE)
-**Added 6 methods with renamed signatures:**
-- `matchWithGroups(long, int)` / `matchWithGroups(ByteBuffer)`
-- `findWithGroups(long, int)` / `findWithGroups(ByteBuffer)`
-- `findAllWithGroups(long, int)` / `findAllWithGroups(ByteBuffer)`
-
-**Naming:** *WithGroups suffix avoids Java overloading conflicts (can't overload by return type)
-
-### 5. Phase 3 Zero-Copy (NATIVE READY - Awaiting User Merge)
-**6 methods planned:**
-- `replaceFirst(long, int, String)` / `replaceFirst(ByteBuffer, String)`
-- `replaceAll(long, int, String)` / `replaceAll(ByteBuffer, String)`
-- `replaceAll(long[], int[], String)` / `replaceAll(ByteBuffer[], String)`
-
-**Status:** ✅ Native build complete, **PR #15 ready to merge**
-- 3 JNI native methods implemented: replaceFirstDirect, replaceAllDirect, replaceAllDirectBulk
-- All 4 platforms built successfully (29 JNI functions verified)
-- Waiting for user to merge PR #15 into feature/replace-operations
-- Then add 6 Java wrapper methods to Pattern.java (~20 lines of code)
-
-### 6. MatchResult AutoCloseable (COMPLETE)
-**Added full safety pattern:**
-- `implements AutoCloseable`
-- `AtomicBoolean closed`
-- `checkNotClosed()` on ALL public methods
-- `close()` method
-- Full JavaDoc explaining try-with-resources requirement
-
-**Was broken:** 35 CaptureGroupsTest failures
-**Fixed:** All tests updated to use try-with-resources pattern ✅
-
-### 7. RE2.java Convenience Methods (COMPLETE)
-**Added 22 static convenience methods:**
-- String operations: match, findFirst, findAll
-- Bulk operations: matchAll, matchAllWithGroups, findAll, filter, filterNot
-- Replace operations: replaceFirst, replaceAll (single + bulk + collection)
-- ByteBuffer operations: matches, matchWithGroups, findWithGroups, findAllWithGroups
-- Utility: quoteMeta
-
-**Total methods:** 25 (was 3)
-**Purpose:** Makes library easier to use without explicit Pattern.compile()
-
-### 8. Bulk Capture Operations (COMPLETE)
-**Added methods:**
-- `MatchResult[] matchAllWithGroups(String[])` - bulk full match with groups
-- `MatchResult[] matchAllWithGroups(Collection)` - collection variant
-- Full metrics instrumentation (Global + Bulk)
-
-**Implementation:** Iterates extractGroups per input (can optimize with native bulk later)
-
-### 7. Native Support (COMPLETE)
-- 29 JNI functions (20 + 6 matching + 3 replace)
-- All 4 platforms built and merged
-
----
-
-## What's FIXED ✅ (Was Broken)
-
-**Tests: All 427 passing** ✅
-
-**Was broken:** 35 failures in CaptureGroupsTest due to MatchResult AutoCloseable
-**Fixed by:** Adding try-with-resources to all MatchResult usages:
-```java
-// OLD (broken):
-MatchResult result = pattern.match("text");
-result.group(1); // Throws: MatchResult is closed
-
-// NEW (correct):
-try (MatchResult result = pattern.match("text")) {
- result.group(1); // Works
-}
-```
-
-**Files needing fixes:**
-- CaptureGroupsTest.java - 24 MatchResult usages
-- Possibly ComprehensiveMetricsTest.java
-- Any other files using MatchResult
-
-**Estimated fix:** 20k tokens (manual try-with-resources wrapping)
-
----

-
----
-
-## Known Issues
-
-### Resolved Issues
-
-**Issue 1: Chronicle Bytes requires Java 17+ JVM arguments**
-- **Status:** RESOLVED
-- **Description:** Chronicle Bytes needs access to JDK internals, requires `--add-opens` flags
-- **Solution:** Added argLine configuration to maven-surefire-plugin with required --add-opens arguments
-- **Impact:** Tests now run successfully on Java 17+
-
-**Issue 2: Heap-backed Bytes don't support addressForRead()**
-- **Status:** RESOLVED
-- **Description:** `Bytes.from(String)` creates heap-backed memory which doesn't provide native addresses
-- **Solution:** Use `Bytes.allocateElasticDirect()` to create off-heap memory instead
-- **Impact:** All tests and helpers use direct memory allocation
-
-**Issue 3: Chronicle Bytes doesn't implement AutoCloseable**
-- **Status:** RESOLVED
-- **Description:** Cannot use try-with-resources for Chronicle Bytes
-- **Solution:** Created `withBytes()` helper method with try-finally and explicit `releaseLast()`
-- **Impact:** Clean resource management in all tests
-
----
-
-## Decision Log
-
-### Decision 1: Maven Shade Plugin for Chronicle Bytes
-- **Status:** DECIDED
-- **What:** Use maven-shade-plugin to relocate Chronicle Bytes classes
-- **Why:** Avoid version conflicts with existing Chronicle libraries in user's JVM
-- **Trade-off:** Larger JAR size vs. guaranteed compatibility
-- **Relocation:** `net.openhft` → `com.axonops.libre2.shaded.openhft`
-
-### Decision 2: Direct Memory Method Naming
-- **Status:** DECIDED
-- **What:** Use `*Direct` suffix for zero-copy methods
-- **Why:** Clear distinction from String-based methods
-- **Examples:** `fullMatchDirect`, `partialMatchDirect`

-## Session Notes
-
-### Session 1 (2025-11-24) - Initial Implementation
-**Work completed:**
-- Created feature branch `feature/chronicle-zero-copy`
-- Created progress tracking file
-- Analyzed existing RE2NativeJNI.java and re2_jni.cpp
-- Added Chronicle Bytes dependency with maven-shade-plugin
-- Implemented 6 new zero-copy JNI methods
-- Created RE2DirectMemory helper class
-- Created correctness tests (DirectMemoryTest.java)
-- Created performance benchmarks (ZeroCopyPerformanceTest.java)
-- Updated workflow to expect 26 JNI functions
-- Triggered native library rebuild via GitHub Actions
-
-**Current copy points identified:**
-1. Java String → JNI GetStringUTFChars() copies to native buffer
-2. JStringGuard class manages this copy with RAII
-3. RE2 uses StringPiece which is zero-copy when given const char*
-4. **Solution:** Pass direct memory address from Chronicle Bytes → skip steps 1 and 2
-
-### Session 2 (2025-11-24) - Testing & Validation
-**Work completed:**
-- Pulled rebuilt native libraries from GitHub Actions
-- Fixed Chronicle Bytes compatibility issues:
- - Added JVM arguments for Java 17+ module access
- - Changed from heap-backed to direct memory allocation
- - Fixed resource management (manual try-finally instead of try-with-resources)
-- All 38 correctness tests passing
-- All 11 performance benchmarks passing
-- **Results:** 45.9% to 99.9% performance improvement depending on input size
-
-**Test results:**
-- DirectMemoryTest: 38/38 tests passed ✅
-- ZeroCopyPerformanceTest: 11/11 benchmarks passed ✅
-- Full test suite: 374/374 tests passed ✅ (no regressions)
-
-### Session 3 (2025-11-24) - Public API Exposure (FINAL)
-
-**Evolution of approach:**
-
-1. **Iteration 1 (rejected):** ZeroCopyPattern adapter classes
- - Problem: Forces users to choose String OR zero-copy
- - Problem: Exposes Chronicle types in public API
-
-2. **Iteration 2:** Raw address/length overloads
- - Added `matches(long address, int length)` etc.
- - Works with any off-heap system
- - But requires manual address extraction
-
-3. **Iteration 3 (final):** Added ByteBuffer API
- - Added `matches(ByteBuffer)` with intelligent routing
- - Direct → zero-copy, heap → String
- - Standard Java, no external dependencies
- - Uses reflection to avoid sun.nio.ch compile dependency
-
-**Final implementation:**
-- Removed ZeroCopyPattern and ZeroCopyRE2 adapter classes
-- Added 10 overloaded methods to Pattern.java:
- - 6 methods accepting (long address, int length)
- - 4 methods accepting (ByteBuffer) with auto-routing
-- Created OffHeapMatchingTest.java - 17 tests
-- Created ByteBufferApiTest.java - 23 tests
-- Uses reflection to extract DirectByteBuffer address (no compile-time dependency)
-- All tests passing
-
-**Design decisions:**
-- ✅ No Chronicle types in public API
-- ✅ ByteBuffer API auto-routes based on isDirect()
-- ✅ Reflection for DirectBuffer.address() (no sun.nio.ch dependency)
-- ✅ Natural mixed usage: String + ByteBuffer + raw address in same Pattern
-
-**Test results:**
-- ByteBufferApiTest: 23/23 tests passed ✅
-- OffHeapMatchingTest: 17/17 tests passed ✅
-- DirectMemoryTest (JNI): 38/38 tests passed ✅
-- Full test suite: 414/414 tests passed ✅ (no regressions)
-
----
-
-## Phase 1 Summary - COMPLETE ✅
-
-### Achievements
-
-**Zero-Copy Implementation Complete:**
-- ✅ 6 new JNI methods for direct memory access
-- ✅ RE2DirectMemory helper class for Chronicle Bytes integration
-- ✅ Native libraries rebuilt for all 4 platforms
-- ✅ 38 correctness tests - all passing
-- ✅ 11 performance benchmarks - all passing
-- ✅ No regressions in existing tests (374 total)
-
-**Performance Results:**
-- **Small inputs (64-256B):** 46-74% faster
-- **Medium inputs (1-4KB):** 90-98% faster
-- **Large inputs (10-100KB):** 99%+ faster
-- **Bulk operations:** 91.5% faster
-
-**Key Insight:** The Direct API maintains constant ~150-200ns/op regardless of input size, while the String API degrades linearly due to copy overhead.
-
----
-
-## Phase 2: Public API Exposure - COMPLETE ✅
-
-### Objectives
-
-Expose zero-copy functionality through clean public API that:
-- Works with ANY off-heap memory system (Chronicle Bytes, DirectByteBuffer, Netty, etc.)
-- Doesn't expose Chronicle types in public API
-- Supports mixed usage (String + off-heap in same app)
-- Zero breaking changes to existing code
-- Intelligent routing (DirectByteBuffer → zero-copy, heap ByteBuffer → String)
-
-### Design Decision: Method Overloading
-
-**Rejected Approach:** Adapter classes like `ZeroCopyPattern`
-- Problem: Assumes all usage is zero-copy (unrealistic)
-- Problem: Exposes Chronicle types in public API
-- Problem: Extra complexity for users
-
-**Chosen Approach:** Simple overloaded methods on Pattern
-- `matches(String)` - existing String API
-- `matches(long address, int length)` - zero-copy for ANY off-heap memory
-- `matches(ByteBuffer)` - auto-routes to zero-copy (direct) or String (heap)
-- Users mix String and off-heap naturally in same app
-
-### Implementation
-
-**Updated Pattern.java:**
-
-Added 10 new overloaded methods in 2 categories:
-
-**Raw Address API** (advanced users, any off-heap system):
-- `matches(long address, int length)` - full match, zero-copy
-- `find(long address, int length)` - partial match, zero-copy
-- `matchAll(long[] addresses, int[] lengths)` - bulk full match
-- `findAll(long[] addresses, int[] lengths)` - bulk partial match
-- `extractGroups(long address, int length)` - capture groups
-- `findAllMatches(long address, int length)` - find all matches
-
-**ByteBuffer API** (standard Java, automatic routing):
-- `matches(ByteBuffer)` - auto-routes: direct→zero-copy, heap→String
-- `find(ByteBuffer)` - auto-routes
-- `extractGroups(ByteBuffer)` - auto-routes
-- `findAllMatches(ByteBuffer)` - auto-routes
-
-**Technical Details:**
-- Uses reflection to extract address from DirectByteBuffer (no compile-time dependency on sun.nio.ch)
-- Falls back gracefully to String API if reflection fails
-- Respects ByteBuffer position/limit without modifying them
-- UTF-8 encoding for heap ByteBuffer conversion
-
-**Helper for Chronicle Users:**
-- `RE2DirectMemory.java` (in jni package) - convenience wrapper accepting Bytes objects directly
-
-**Tests:**
-- `OffHeapMatchingTest.java` - 17 tests with Chronicle Bytes (address/length API)
-- `ByteBufferApiTest.java` - 23 tests with ByteBuffer (auto-routing)
-- All tests verify off-heap results match String API results
-
-### Test Results
-
-- **ByteBufferApiTest:** 23/23 tests passed ✅
-- **OffHeapMatchingTest:** 17/17 tests passed ✅
-- **DirectMemoryTest (JNI layer):** 38/38 tests passed ✅
-- **Full test suite:** 414/414 tests passed ✅
-- **No regressions**
-
-### Usage Examples
-
-**Option 1: ByteBuffer (Standard Java, Auto-Routing)**
-```java
-Pattern pattern = Pattern.compile("\\d+");
-
-// DirectByteBuffer - automatically uses zero-copy (46-99% faster)
-ByteBuffer directBuffer = ByteBuffer.allocateDirect(1024);
-directBuffer.put("12345".getBytes(StandardCharsets.UTF_8));
-directBuffer.flip();
-boolean r1 = pattern.matches(directBuffer); // Zero-copy!
-
-// Heap ByteBuffer - automatically falls back to String
-ByteBuffer heapBuffer = ByteBuffer.wrap("67890".getBytes());
-boolean r2 = pattern.matches(heapBuffer); // String conversion
-
-// Mix them naturally
-boolean r3 = pattern.matches("abc"); // String API
-```
-
-**Option 2: Chronicle Bytes (Raw Address API)**
-```java
-Pattern pattern = Pattern.compile("\\d+");
-
-// Extract address/length from Chronicle Bytes
-Bytes bytes = Bytes.allocateElasticDirect();
-try {
- bytes.write("67890".getBytes(StandardCharsets.UTF_8));
- long address = bytes.addressForRead(0);
- int length = (int) bytes.readRemaining();
- boolean matches = pattern.matches(address, length); // 46-99% faster!
-} finally {
- bytes.releaseLast();
-}
-```
-
-**Option 3: Bulk Matching (Chronicle Bytes)**
-```java
-Pattern pattern = Pattern.compile("valid_.*");
-Bytes[] bytesArray = ...; // Multiple off-heap buffers
-
-// Extract addresses/lengths
-long[] addresses = new long[bytesArray.length];
-int[] lengths = new int[bytesArray.length];
-for (int i = 0; i < bytesArray.length; i++) {
- addresses[i] = bytesArray[i].addressForRead(0);
- lengths[i] = (int) bytesArray[i].readRemaining();
-}
-
-boolean[] results = pattern.matchAll(addresses, lengths); // 91.5% faster!
-```
-
-**Option 4: Mixed Usage (Real-World)**
-```java
-Pattern emailPattern = Pattern.compile("[a-z]+@[a-z]+\\.[a-z]+");
-
-// Process different data sources with same pattern
-boolean r1 = emailPattern.matches("user@example.com"); // String
-
-ByteBuffer networkBuffer = getNetworkBuffer(); // DirectByteBuffer from Netty
-boolean r2 = emailPattern.find(networkBuffer); // Zero-copy
-
-Bytes chronicleBytes = getFromCache(); // Chronicle Bytes
-long addr = chronicleBytes.addressForRead(0);
-int len = (int) chronicleBytes.readRemaining();
-boolean r3 = emailPattern.matches(addr, len); // Zero-copy
-
-// All work with same Pattern instance!
-```
-
-### Architecture Benefits
-
-✅ **No Chronicle types in public API** - accepts raw `long address`, `int length`, or `ByteBuffer`
-✅ **Works with ANY off-heap system** - Chronicle Bytes, DirectByteBuffer, Netty ByteBuf, etc.
-✅ **Intelligent routing** - ByteBuffer API auto-detects direct vs heap and routes appropriately
-✅ **Natural mixed usage** - String and off-heap in same app, same Pattern
-✅ **Zero breaking changes** - existing String API unchanged
-✅ **Simple API** - just overloaded methods, no adapters needed
-✅ **Standard Java support** - ByteBuffer is java.nio (no external deps needed)
-✅ **Reflection-based** - No compile-time dependency on sun.nio.ch.DirectBuffer
-✅ **Helper available** - RE2DirectMemory for Chronicle Bytes convenience (optional)
-
----
-
-## Next Steps (Future Phases)
-
-**Phase 3: Chronicle Map Cache (Optional)**
-- Replace PatternCache with Chronicle Map for off-heap caching
-- Further reduce GC pressure
-- Optional persistence for fast restarts
-
-**Phase 4: NUMA Optimization (Advanced)**
-- Per-NUMA-socket caches using Chronicle Thread Affinity
-- Topology-aware pattern distribution
-- For multi-socket servers only
-
----
-
-## Final Summary
-
-### What Was Delivered

-
-**Dropwizard Metrics integration with automatic JMX**
-
----
-
-## Overview
-
-The `libre2-dropwizard` module provides convenient integration with Dropwizard Metrics, including automatic JMX exposure. Use this module if your application already uses Dropwizard Metrics (Cassandra, Spring Boot, Dropwizard apps, etc.).
-
----
-
-## Installation
-
-```xml
-
- com.axonops
- libre2-dropwizard
- 0.9.1
-
-
-```
-
----
-
-## Quick Start
-
-### Basic Usage
-
-```java
-import com.axonops.libre2.dropwizard.RE2MetricsConfig;
-import com.axonops.libre2.api.Pattern;
-import com.axonops.libre2.cache.PatternCache;
-import com.codahale.metrics.MetricRegistry;
-
-// Get your application's MetricRegistry
-MetricRegistry registry = getYourMetricRegistry();
-
-// Create RE2 config with metrics (choose your prefix)
-RE2Config config = RE2MetricsConfig.withMetrics(registry, "com.myapp.regex");
-
-// Set as global cache
-Pattern.setGlobalCache(new PatternCache(config));
-
-// Use normally
-Pattern pattern = Pattern.compile("test.*");
-Matcher matcher = pattern.matcher("test123");
-boolean matches = matcher.matches();
-
-// All 21 metrics now in your MetricRegistry + JMX automatically
-```
-
----
-
-## Integration Examples
-
-### Cassandra Integration
-
-```java
-import com.axonops.libre2.dropwizard.RE2MetricsConfig;
-
-// Get Cassandra's MetricRegistry
-MetricRegistry cassandraRegistry = getCassandraMetricRegistry();
-
-// Use convenience method (sets standard Cassandra prefix)
-RE2Config config = RE2MetricsConfig.forCassandra(cassandraRegistry);
-Pattern.setGlobalCache(new PatternCache(config));
-
-// Metrics appear under: org.apache.cassandra.metrics.RE2.*
-// Visible via: nodetool, JConsole, Prometheus JMX exporter
-```
-
-### Spring Boot Integration
-
-```java
-import com.axonops.libre2.dropwizard.RE2MetricsConfig;
-import org.springframework.beans.factory.annotation.Autowired;
-
-@Autowired
-private MeterRegistry meterRegistry; // Spring's registry
-
-// Convert Spring's MeterRegistry to Dropwizard (if needed)
-// Or if Spring Boot uses Dropwizard metrics directly:
-MetricRegistry dropwizardRegistry = getDropwizardRegistry();
-
-RE2Config config = RE2MetricsConfig.withMetrics(dropwizardRegistry, "com.mycompany.myapp.regex");
-Pattern.setGlobalCache(new PatternCache(config));
-```
-
-### Standalone Application
-
-```java
-import com.axonops.libre2.dropwizard.RE2MetricsConfig;
-import com.codahale.metrics.MetricRegistry;
-import com.codahale.metrics.jmx.JmxReporter;
-
-// Create your own registry
-MetricRegistry registry = new MetricRegistry();
-
-// Configure RE2
-RE2Config config = RE2MetricsConfig.withMetrics(registry, "com.mycompany.appname.re2");
-Pattern.setGlobalCache(new PatternCache(config));
-
-// Metrics automatically exposed via JMX (RE2MetricsConfig handles this)
-// Or manually configure JmxReporter:
-JmxReporter jmxReporter = JmxReporter.forRegistry(registry).build();
-jmxReporter.start();
-```
-
----
-
-## Metric Prefix Configuration
-
-The metric prefix determines where your metrics appear in JMX and monitoring systems:
-
-| Framework | Recommended Prefix | JMX ObjectName Example |
-|-----------|-------------------|------------------------|
-| Cassandra | `org.apache.cassandra.metrics.RE2` | `org.apache.cassandra.metrics:type=RE2,name=patterns.compiled` |
-| Spring Boot | `com.mycompany.myapp.regex` | `com.mycompany.myapp.regex:type=patterns,name=compiled` |
-| Standalone | `com.axonops.libre2` | `com.axonops.libre2:type=patterns,name=compiled` |
-| Custom | Whatever you want | Depends on your prefix |
-
----
-
-## The 21 Metrics
-
-All metrics are automatically registered in your MetricRegistry:
-
-### Pattern Compilation (5 metrics)
-- `patterns.compiled` (Counter) - Total patterns compiled
-- `patterns.cache_hits` (Counter) - Cache hit count
-- `patterns.cache_misses` (Counter) - Cache miss count
-- `patterns.compilation_time` (Timer) - Compilation latency
-- `patterns.invalid_recompiled` (Counter) - Auto-recompiled patterns
-
-### Cache Eviction (6 metrics)
-- `cache.evictions_lru` (Counter) - LRU evictions
-- `cache.evictions_idle` (Counter) - Idle evictions
-- `cache.evictions_deferred` (Counter) - Deferred evictions
-- `cache.size` (Gauge) - Current cache size
-- `cache.native_memory_bytes` (Gauge) - Off-heap memory used
-- `cache.native_memory_peak_bytes` (Gauge) - Peak memory
-
-### Resource Management (4 metrics)
-- `resources.patterns_active` (Gauge) - Active patterns
-- `resources.matchers_active` (Gauge) - Active matchers
-- `resources.patterns_freed` (Counter) - Patterns freed
-- `resources.matchers_freed` (Counter) - Matchers freed
-
-### Performance (3 metrics)
-- `matching.full_match` (Timer) - Full match latency

-
-### Errors (3 metrics)
-- `errors.compilation_failed` (Counter) - Compilation failures
-- `errors.native_library` (Counter) - Native library errors
-- `errors.resource_exhausted` (Counter) - Resource limits hit
-
----
-
-## JMX Monitoring
-
-Once configured, metrics are accessible via JMX:
-
-### Using JConsole
-
-1. Connect to your application's JMX port
-2. Navigate to MBeans tab
-3. Find your metric prefix (e.g., `com.myapp.regex` or `org.apache.cassandra.metrics.RE2`)
-4. Expand to see all 21 metrics
-
-### Using Command Line (jmxterm)
-
-```bash
-# Install jmxterm
-brew install jmxterm
-
-# Connect and query
-java -jar jmxterm.jar -l localhost:7199
-> domains
-> domain com.axonops.libre2
-> beans
-> get -b com.axonops.libre2:type=patterns,name=compiled
-```
-
-### Cassandra-Specific Monitoring
-
-```bash
-# Using nodetool
-nodetool sjk mx -q 'org.apache.cassandra.metrics:type=RE2,*'
-
-# View all RE2 metrics
-nodetool sjk mx -b org.apache.cassandra.metrics:type=RE2,name=patterns.compiled
-
-# Watch cache size
-watch -n 5 "nodetool sjk mx -b org.apache.cassandra.metrics:type=RE2,name=cache.size"
-```
-
----
-
-## Logging Configuration
-
-All logs are produced via SLF4J. See [LOGGING_GUIDE.md](../LOGGING_GUIDE.md) for comprehensive documentation.
-
-### Quick Configuration
-
-**Logback (Cassandra, Spring Boot):**
-```xml
-
-
-
-```
-
-**Log4j2:**
-```xml
-
-
-
-
-
-```
-
-All logs are prefixed with "RE2:" for easy filtering.
-
----
-
-## API
-
-### RE2MetricsConfig
-
-**Main factory class for creating RE2Config with metrics:**
-
-```java
-// Generic (specify your prefix):
-RE2Config withMetrics(MetricRegistry registry, String metricPrefix)
-RE2Config withMetrics(MetricRegistry registry, String metricPrefix, boolean enableJmx)
-
-// Default prefix (com.axonops.libre2):
-RE2Config withMetrics(MetricRegistry registry)
-
-// Cassandra convenience (uses org.apache.cassandra.metrics.RE2):
-RE2Config forCassandra(MetricRegistry cassandraRegistry)
-```
-
----
-
-## Examples
-
-See [examples/](../examples/) directory for complete examples:
-- Standalone application
-- Cassandra integration
-- Spring Boot integration
-- Custom monitoring setup
-
----
-
-## Requirements
-
-- Java 17+
-- Dropwizard Metrics 4.2.x (provided by your application)
-- libre2-core 0.9.1
-
----
-
-## Performance
-
-**Metrics overhead:** < 1%
-- Counter increment: ~10-20ns
-- Timer recording: ~50-100ns
-- Gauge registration: one-time cost
-
-**Zero overhead option:** Don't use this module, just use `libre2-core` with default NoOp metrics.
