Define soon. Progress is being made. The more folks that contribute
(particularly patches and reviews of proposed patches) the faster that
progress will be. There is no set date I am aware of.

I'll note at this point there has been an awful lot of people demanding
more progress in BCEL and very few actually stepping up and contributing.

As long as BCEL is in Commons proper then that is a reasonable expectation.

Tomcat depends on BCEL so it is a safe bet that BCEL will be updated to
handle any parsing issues that emerge with new bytecodes. However,
Tomcat depends on fork of the source so it doesn't drive BCEL releases.

Sounds reasonable to me. Open a Jira, provide the patch and someone
should take a look.

Only you can make that choice.
