Thanks @echonesis for the patch. Striped#custom(int, Supplier) is now public in Guava, so we can remove reflection without moving to Guava's package.

Thanks @adoroszlai for mentioning.
I've updated it in the latest commit.

Thanks @echonesis for updating the patch. I think we can replace calls of SimpleStriped.custom with Striped.custom, and completely remove both SimpleStriped.custom and TestSimpleStriped.testCustomStripes.
