According to the spec (or at least the intent of the spec), once the
EntityManager is closed, it should not be retrieving data from the database,
which is exactly why TopLink's behavior is wrong. This feature was left in
the TopLink implementation to help novice developers sidestep the
LazyInitializationException that Hibernate throws. The consequence is that
it completely breaks the guarantees that the persistence context affords
you.
