Barry Kaplan commented on EJB-215:
----------------------------------

The changes are passing all my tests! Thanks very much. 

One side effect is that I now get the error "Foreign key circularity dependency involving the following tables: ..."

These classes have not changed since I have upgraded the new build. One of the classes does not even depend on either of the other two. Do you know of any class' logging I can crank up to see more details?

> As per the JPA spec, an EntityManager should be closable prior to the end of the transaction. At least in the scenario where an exception is thrown during commit, AbstractEntityManagerImpl will attempt to mark the transaction rollback only, but in doing so it will access the Session. The session checks if it is closed, and if so throws an exception. There may be other scenarios where closing the EM prior to transaction end cause incorrect failures.
