> Fields of an entity instance are nulled after calling EntityManager.remove() on an instance.
> For example, I have an entity class named User. I persist and then remove an instance
of User.
> //
> // EntityManager em is initialized before the following code
> //
> em.getTransaction().begin();
> User user = new User();
> user.setName("name1");
> em.persist(user);
> em.getTransaction().commit();
> System.out.println(user.getName); // will print out name1
> em.getTransaction().begin();
> em.remove(user);
> em.getTransaction().commit();
> System.out.println(user.getName); // will print out null (oh no!) 
> After I persist and remove the same instance of User, it's fields became null. I believe
this shouldn't be the case as Section "3.2.3 Removal" of the 2.0 spec states:
> "After an entity has been removed, its state (except for generated state) will be that
of the entity at the point at which the remove operation was called."
