JBAS-9378 is now AS7-488, due to the recent separation of AS7 jiras.  I 
also retitled it to be more reflective of the specific underlying issue 
to be solved.

There are larger scope issues not covered by AS7-488.  Clustering the 
second level cache properly, is not covered and not yet in JIRA.

A related effort, is switching to Hibernate 4.0 (AS7-396), which will 
happen on a separate branch.  Steve and I, are hacking away against 
https://github.com/scottmarlow/jboss-as/tree/hibernate40_2 for this 
effort.  I'm thinking that our efforts to solve the classloader issues, 
behind the 2LC failure, will go into Hibernate 4.0.

So, there are definitely bigger scopes involved (in clustering and 
Hibernate integration).
