--------------------------------------------------------------

That's right, but we should not make things worse. If one API allows to swap instructions
on handle, the handle should not fail if the swapped instruction is requested.

BTW "meant to be used" is not "shall be used only for".

> 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.
