"Persistence provider caller does not implement the EJB3 spec correctly." warning when deploying on JBoss 5.1.0.GA

Question

i get this hibernate warning pretty much every time i deploy a persistence unit on JBoss. its never the cause of any issues, but i was wondering if anyone knows what exactly this means, and can it be fixed/slicenced/worked-around in some way.

According to this comment from Jaikiran Pai (RedHat employee member of the JBoss EJB3 development team):

There is a warning that may stick together with the error:

2010-09-12 12:10:52,759 WARN  [org.hibernate.ejb.Ejb3Configuration] (HDScanner) Persistence provider caller does not implements the EJB3 spec correctly. PersistenceUnitInfo.getNewTempClassLoader() is null.

You can ignore that log message.

That's the best answer I've found so far about the warning (which is reported in EJBTHREE-710 without any particular comment...).
