It seems that you use some older build version - there were several bugs in the
logging integration that had been fixed so that you get real messages.
That said, you should see plenty of TopLink messages at the FINEST level at
least when the PU is being loaded.
Are you using default transaction setting? Is em.merge() the only access to the
entity manager? Can it be that you call em.clear() before the transaction commits?
