Concern over CGLIB's inactivity is certainly valid. However, our internal load-testing
of javassist (a few months back) revealed that the library's perf characteristics
aren't quite ready for prime time. In some cases, our system performed 2x faster with
cglib v. javassist. I don't recall the exact reason why, but possibly this was due to
excess synchronization in javassist code (I could be wrong about this though).

Its more than just inactivity. As projects mature you expect some
inactivity; its just the nature of the beast. What was more the issue
was our attempts to contact the developers going unanswered. We tried
for over a year to contact the CGLIB developers about this need for a
release and got no response at all. That's when this decision was made.
See this JIRA case and its links for the history here:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2222
You might also want to check out
http://opensource.atlassian.com/projects/hibernate/browse/HHH-3832
which is the upgrade to the since released CGLIB 2.2

Pardon as this is slightly off-topic, but does anyone know where to get (buildable)
sources for cglib 2.2?
2.1_3's Enhancer.getCallbacksSetter() (that is called by CGLIbProxyInitalizer)
reflects on target class, and as that calls is made every time a proxy created, the cost
of reflection starts to add up. I'd like to cache results of that method in a
hashmap.
Thanks,
-nikita
