In a setup using JTASessionContext flush() and close() should occur automatically at the end of the transaction.

This works with hibernate 3.0.5 but does not with hibernate 3.2.0-ga and 3.2.1-ga.

Setup:
hibernate.transaction.manager_lookup_class=org.hibernate.transaction.JBossTransactionManagerLookup
hibernate.current_session_context_class=org.hibernate.context.JTASessionContext
hibernate.transaction.flush_before_completion=true
hibernate.transaction.auto_close_session=true

Usage:
    public void doSomeWork() throws Exception {
        TransactionManager tm = (TransactionManager) Locator.lookup("java:/TransactionManager");
        tm.begin();

        Session session = sf.getCurrentSession();
        PersistentObject data = new PersistentObject ();
        data.setXYZ("xyz");
        session.save(data);

        tm.commit();
    }

Symptom:
no inserts/updates/deletes, only "select xxx.nextval()" occur to the database.
