Katsuya commented on BCEL-221:
------------------------------

Hi,

I’m interested in contributing to this issue (BCEL-221: BCELifier is not 
working for Java8Example).  
I have reproduced the problem locally (ConstantPool at index 0 is null when 
running BCELifier on Java8Example).  

Before starting a patch:
- Could you confirm whether anyone is already working on this?  
- Are there any guidelines for contributing or tests to run against before 
submitting a fix?

If the direction is valid, I’d like to work on it and prepare a PR.

Thanks in advance.
