While I do think that BCEL has miserably failed from the

That actually could be a good summer project... E.g. build some intermediate bridge that would use ASM underneath or some kind of source code analyzer/transformer to help with straight migration from BCEL to ASM tree API (maybe even as simple as Jackpot rules, or somehow reuse Eclipse's binary refactorings). I've been looking on such conversion process at some point and it seems there is big similarity between BCEL and ASM.
From the API perspective the BCEL approach is surely a bit more
straight forward than ASM ...and easier to handle in some areas.
Also performance was never an issue for me yet.
We've been asking users how to make tree API easier to use in ASM. So, what exactly are those areas that easier to handle with BCEL?

BTW, Eric just posted proposal for changes in tree API for ASM 3, which should address several old issues, including random insertion into the list of method instructions and improved performance of scanning trough instructions to another 8%.
But starting a new project as a user I would probably go with ASM
as this community just rocks. They have a kick-ass eclipse plugin
and they support their user base very well.
 I guess we do. :-)   But we could use some feedback...
