[dependabot]

Bumps org.mozilla:rhino from 1.7.12 to 1.7.14.1.

Release notes

Sourced from org.mozilla:rhino's releases.

Rhino 1.7.14.1

This release fixes a problem with formatting of floating-point numbers to strings that may result in very bad performance in some cases.

Projects that are unable to upgrade to Rhino 1.8.1, or unable to upgrade to at least Java 11, should use this release.

Rhino 1.7.13

Script Engine support

Now that Nashorn has been deprecated, a number of poeple have asked about using Rhino with the standard Java "ScriptEngine" interface. This release supports that.

However, in order to avoid breaking existing code, the script engine is shipped in a separate JAR. Use the "rhino-engine" jar along with the standard "rhino" jar to include this feature.

Generator Support

This release supports generators based on the ES6-standard "function *" syntaxt.

Other important changes

This release also includes a number of quality and consistency fixes from five contributors. As always, check out the compatibility table to see where Rhino stands today.

Gregory Brail (18):

• Start on 1.7.13.
• Add a build config for CircleCi.
• Upgrade Gradle version to 6.5.
• Update max workers.
• Add support for ES6 generators.
• Make "GeneratorFunction" pattern work in interpreted mode.
• Complete implementation of GeneratorFunction.
• Diagnostics to discover test timeouts.

Changelog

Sourced from org.mozilla:rhino's changelog.

Rhino 1.8.1, Rhino 1.7.15.1, Rhino 1.7.14.1

December 2, 2025

These releases fix a bug in the code that formats floating-point numbers into strings that could result in very bad performance in some cases.

We recommend that all users of Rhino upgrade to release 1.8.1 if possible, and upgrade to Java 17 or 21.

Users who need an older release, or who cannot yet leave Java 8, can also use 1.7.15.1 or 1.7.14.1.

Rhino 1.8.0

January 2, 2025

Rhino 1.8.0 contains some significant changes, so we're incrementing the final version number for the first time in a very long time. Here are a few highlights:

• Rhino now requires Java 11 minimum. We currently test against Java 11, 17, and 21.
• Rhino has been broken down into individual Java modules that are properly encapsulated as Java Modules. See README.md for a breakdown of which modules are which -- short answer is that everyone will need the "rhino" module and many will need others.
• Older code not able to adapt to using multiple JARS can still use the "rhino-all" module, which publishes an "all-in-one" JAR like the old "rhino.jar".
• The default language level is "VERSION_ES6". That means that modern JavaScript features supported by Rhino will work by default.
• There are big improvements in compatibility, including support for "super", reflect and proxy, and lots of other language features. See the compatibility table for the details.

Thanks to all who contributed -- we had 24 contributors to this release, with some new contributors who added significant capabilities. Please keep the contributions and attention coming!

Rhino 1.7.15

May 3, 2024

Highlights of this release include:

• Improvements in Unicode support
