| Sice Hibernate ORM > 5.1 there seems to be a problem with ForeignGenerator when using Hibernate with a JTA transaction manager in conjuncton with Spring 4.3+. When not explicitly flusing the entity manager within the transaction, the EntityManager and the Hibernate session is logically closed before the transaction is commited and hence before the hibernate session is flushed. This is a spring handling within org.springframework.transaction.support.ResourceHolderSynchronization.beforeCompletion() The problem is, that the ForeignGenerator uses Session.contains performing a close-check after the session has been closed.
org.springframework.transaction.UnexpectedRollbackException: JTA transaction unexpectedly rolled back (maybe due to a timeout); nested exception is bitronix.tm.internal.BitronixRollbackException: RuntimeException thrown during beforeCompletion cycle caused transaction rollback
