----------------------------------------
When will this problem be resolved? I've recently upgraded to 4.0.4GA and now I get
the above error. Additionally, I'm getting a related PermGen error:

Javassist lazy proxy factoring not thread-safe
----------------------------------------------
Key: HIBERNATE-46
URL: http://jira.jboss.com/jira/browse/HIBERNATE-46
Project: Hibernate
Issue Type: Bug
Environment: JBoss AS 4.0.4 with EJB 3-RC8
Reporter: Ortwin Glück
Assigned To: Steve Ebersole
Multiple threads may simultanously (especially on SMP systems) create proxy classes for
the first time. The JavassistLazyInitializer is not completely thread safe. So the first
thread will successfully create the dynamic class, while a second thread may fail. We saw
this happen a few times at JBoss startup when multiple messages from other systems arrived
via JMS (quite normal when you take your PROD system down for some minutes, as work keeps
queuing up). So multiple MDB threads were running the same transactions (using the same
classes) and thus the probability for this error to occur is close to 100%.
The situation can easily be solved by proper synchronization inside the
JavassistLazyInitializer.
