> In some use case, an unexpected pre/postUpdate callback event will be fired. 
> The following operations demonstrate the scenario:
> 			em.getTransaction().begin();
> 			// Create and persist a new Message entity
> 			Message message = new Message("Hello Persistence!");
> 			message.setId(1);
> 			em.persist(message);
> 			em.flush();
> 			// Create and persist another new Message entity
> 			message = new Message("Hello Persistence 2!");
> 			message.setId(2);
> 			em.persist(message);
> 			em.getTransaction().commit();
> 			em.getTransaction().begin();
> 			message.setMessage("Mutated 2!!");
> 			em.getTransaction().commit();
> ** PrePersist - Message: id=1, m=Hello Persistence!, create=null, updated=null, v=null
> ** PostPersist - Message: id=1, m=Hello Persistence!, create=null, updated=null, v=1
> ** PrePersist - Message: id=2, m=Hello Persistence 2!, create=null, updated=null, v=null
> ** PreUpdate - Message: id=1, m=Hello Persistence!, create=null, updated=null, v=1
> ** PostPersist - Message: id=2, m=Hello Persistence 2!, create=null, updated=null, v=1
> ** PostUpdate - Message: id=1, m=Hello Persistence!, create=null, updated=null, v=1
> ** PreUpdate - Message: id=2, m=Mutated 2!!, create=null, updated=null, v=1
> ** PostUpdate - Message: id=2, m=Mutated 2!!, create=null, updated=null, v=2
