Description

During bytecode generation of an expression of the form S1<S2, where S1 and S2 are statically known to be single strings, the code generator attempts to generate a call on a static method CodepointCollator.compareCS(CharSequence, CharSequence). But this method is not static, so it fails with a NoSuchMethodException.

Also, unhelpfully, the exception does not include details of the method that was being called.

Reported by Thorsten Rohm in private email.

  • Status changed from In Progress to Resolved

Fixed this by the simple expedient of making the method static. (Note the patch needs to convert other invocations of the method to static invocations)

Also improved the diagnostics.

Patch committed to Subversion on the 9.6 and 9.7 branches.
