> I have a junit test case that persists something, finds it, then deletes it and tries to find again.
> Second time round, find() fails with an ObjectDeletedException. This is the semantics of Session.load(), not EntityManager.find(), which is meant to return null if something cannot be found:
>     public void testDeleteAndFindFailsWrong() throws Exception {
>         Event event = createTestEvent();
>         String key = event.getKey();
>         EntityTransaction transaction = null;
>         try {
>             transaction = manager.getTransaction();
>             transaction.begin();
>             manager.persist(event);
>             Event e2 = manager.find(Event.class, key);
>             assertEquals(event, e2);
>             manager.remove(e2);
>             try {
>                 e2 = manager.find(Event.class, key);
>                 assertNull("The spec says that find should return null here", e2);
>             } catch (ObjectDeletedException e) {
>                 fail("This is not in the spec"+e);
>             }
>         } finally {
>             rollback(transaction);
>         }
>     }
