Javassist 3.11 no good?

I'm getting class loader errors with Javassist 3.11 ... I'm reverting
to 3.9 and they go away.

I have some ideas for API changes to start putting the amount of
dynamic code generated on a diet and eventually allow for a transition
to a non-Javassist method of bytecode enhancement.

I was hoping that 3.11 would be *more* (not *less*) compatible with
JDK 1.6.  Oh well.

I've also had weird classloader issues with 3.11.0 and Tapestry.  Had
to revert back to 3.10.0 to get things working again.

Indeed 3.11 has caused me class loading issues on various projects on
various machine (all unix) with various JDK but all 1.6 so i guess
there's something.
I didn't have had the time to go deeper since all projects (3) even if
they use the current trunk they're in production (they're all internal
applications which make things easier for me)

As already said reverting to 3.9 makes everything works as expected.

Not have the needs for any particular API present in 3.11 and not in
3.9 makes the choice to stick with 3.9 the good one, while looking at
a transition to leave javassist could be good. ASM has worked nicely
for me and the time could be good too.

Cheers

Then It all starts to become very restrictive, nice but very restrictive.

Actually, I meant it as a rule for all dependencies Tapestry has at
the time of a release - they all need to exist in central

I don't see it in the near future but it would be nice to have...

You're talking about https://jira.jboss.org/jira/browse/JASSIST-96 ?
Perhaps there's a reason for it being a pain - i prefer to just trust as few
repos as possible (helps with repeatable builds, a better world, e.t.c.).
In fact, i've read that central will only accept artifacts that don't depend on
other repos - not sure when this will be enforced but it makes sense.

Anyway, perhaps we need to run a vote on the matter...

Well, then you get into the business of submitting JARs to the central
maven repository which is a pain. JBoss maintains a perfectly good
repo ... the problem is that Javassist 3.11 misbehaves (on mine and
other machines).

Actually at some point i've done a similar update in the 5.0 branch (i think)
but then i noticed that 3.11 is not available in central (see
http://mirrors.ibiblio.org/pub/mirrors/maven2/javassist/javassist/ )
so I reverted back.
It's also considered a best practice to not require any external repositories
other than central - how about sticking to that?
