JmhBytecodeGenerator is incompatible with any module-info stuff

[cpw]

Describe the bug You're using JmhBytecodeGenerator, which seems to have been pretty much abandoned upstream and is completely incompatible with any module-info related artifacts.

To Reproduce Steps to reproduce the behavior:

1. Specify a module-info in any jmh related artifact to be processed by gradle plugin
2. Try and run
3. See error

 ./gradlew jmh

Version: 5.0.7

I've tried the asm generator, but that has similar difficulties

./gradlew jmh

Looking upstream it seems this particular generator (bytecode) is not getting a lot of attention and hasn't for some time. The only focus is in the annotation processor, which you seem to have specifically abandoned.

I can't figure out any way to change to using the annotation processor with the gradle plugin sadly.
