> h5. PREFACE
> I'm trying to port FindBugs to the latest greatest BCEL 6 state from trunk, see https://github.com/findbugsproject/findbugs/issues/106.
> In short, FindBugs was using some manually created BCEL 5.2 fork which allowed us somehow run BCEL on Java 8 and even Java 9.
> Unfortunately I have no idea how to rebuild that fork, because no one in the project left any documentation.
> So anyway, my goal was to use unmodified BCEL6, therefore I fixed all compile issues caused by BCEL-222 ((n)) and was able to run FB with BCEL6 head.
>  
> Unfortunately I found some regressions.
> h5. Environment
> I'm using my own git clone from BCEL mirror https://github.com/iloveeclipse/commons-bcel/commits/trunk
> The clone only adds few Eclipse files and fixes some obvious errors, nothing worth to mention here. The reason why I'm not using svn because it is too slow and I won't waste my time.
> To see commits I needed to port FB to BCEL6 port, go to https://github.com/findbugsproject/findbugs/tree/java9_bcel6
> h5. How to reproduce
> {code}
> git clone https://github.com/findbugsproject/findbugs.git
> cd findbugs
> git checkout java9_bcel6
> cd findbugs
> ant
> cd findbugsTestCases
> ant
> {code}
> You should run Java 8.
> After running tests, you should see many various errors, like: https://github.com/findbugsproject/findbugs/files/300401/bcel6_test_result.txt
> None of those error appear with the old private patched BCEL5.2 snapshot we've used before.
> It would be nice to fix the errors before the BCEL release.
