[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Injected EntityManager in SLSB after an exception

Environment: JBoss AS 4.0.5, Hibernate 3.2.5, Hibernate EM 3.3.1

I am using CMP.  I have an injected entitymanager (em) in an SLSB I use to persist new rows into the DB.

After an exception is thrown (in this case a dup key) -  subsequent calls to the SLSB method that does the persist seems to be using the same em that was rendered unusable by the exception. 

I say "unusable" because per Hibernate documentation an em must be closed after an exception. BUT: I am using CMP with @PersistenceContext for injection so the container should handle that. Right?  I would think the container would inject a new em for the next call to the SLSB method????    Is there something I must do to force the new em to be injected?  

On the first insert with a dup key I get an EntityExistsException (this is expected).  But, on the next call to the SLSB I get the stack trace below which to me indicates the SLSB still has the old em and is trying to use it:
