Description

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 () and was able to run FB with BCEL6 head.

Unfortunately I found some regressions.

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

How to reproduce

git clone https://github.com/findbugsproject/findbugs.git
cd findbugs
git checkout java9_bcel6
cd findbugs
ant
cd ../findbugsTestCases
ant

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.
