Performance issues when migrating from JBoss 4.2.2 to EAP 5.0

Solution Verified - Updated -

Issue

An existing J2EE application, with lots of BMP's, CMP's, session beans and so on, is working perfectly on Jboss AS 4.2.2; however, the same application runs very slowly on JBoss 5.0.0, we think this issue is related to the way we are using one of the BMPs, which behaves as a session bean, but we don't know for sure if that is the reason.
One of the process that takes 5 seconds on Jboss 4.2.2, takes about 9 minutes on Jboss 5.0.0. this is the big issue, it works but is too slow.

Environment
