[hibernate-dev] JdbcSession proposal

[Scott Marlow]

I pushed a test case that simulates what can happen with remote EJB 
invocations that share the same JTA transaction & EntityManager.  The 
"Transaction was rolled back in a different thread!" error [2] is thrown 
but shouldn't be, since the active application thread has changed to a 
different thread (which can happen).  The workaround is to set 
"hibernate.jta.track_by_thread" to false.

I think that we need to save the thread id at the start of every 
application call into the EntityManager.
