Turn logging on to finest and see when a beginTransaction() call occurs on
the TopLink session.
Also check if any exceptions are occurring.
What are you doing exactly to recreate the issue, try to narrow down the
cause.
Are you executing any native SQL, or queries using pessimistic locking?
They may be triggering a begin of a transaction that the EntityManager is
not aware of.
