Message Title

The problem is that Springframework ORM (JPA subpackage) closes the entity manager During

triggerBeforeCompletion(status)

WIth some analysis I found that
TransactionalEntityManagerSynchronization (org.springframework.orm.jpa.EntityManagerFactoryUtils) closes the entityManager too early and there's no way to configure or change the following:

org.springframework.transaction.support.ResourceHolderSynchronization<H, K>

	protected boolean shouldReleaseBeforeCompletion() {
		return true;
	}

In hibernate 4.x there's no problem because the EntityManager and hibernate Session are two different instances and closing the entity manager won't always close the hibernate session. In hibernate 5.2.x they are the same instance.

I created a small setup where I can reproduce the issue. Please find it attached.
