Thanks for asking.

You are correct that this is not an area to help debug users programs.  
The more you have reasonable cause to suspect that javac may not be 
behaving correctly, (or could reasonably be improved) and the more you 
can produce evidence, such as reproducible test cases, to back up your 
claim, the more interested folk will be in general. Ideally, test cases 
should be small, and should be "just pure javac" -- meaning, so simple 
there's no need to involve any build tools, unless you believe they are 
an inherent part of the problem.

If you file an issue on, and you don't hear back in a 
timely manner, you can try posting a reference here and we can help 
ensure the issue is migrated to
