EntityManager.find() is supposed to return null when the entity is not in the DB. This works except under this condition. I'm seeing this in a unit test of mine, hence the odd use-case (I'm deleting the resource and then immediately trying to find it again), but it does seem like its not behaving properly in that case. Do this to replicate: Pojo pojo = new Pojo(); | entityManager.persist(pojo); | int id = pojo.getId(); | entityManager.remove(pojo); | assert entityManager.find(Pojo.class, id) == null; // this throws exception find() should return null in this case, but I get this exception: javax.persistence.EntityNotFoundException: org.hibernate.ObjectDeletedException: The object with that id was deleted: [Pojo#506554] | at org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:564) | at org.hibernate.ejb.AbstractEntityManagerImpl.find(AbstractEntityManagerImpl.java:168) | ... I was wondering if anyone else sees this, and if its truly the way its designed to work. Again, it is an odd use case and one I'm only using in a unit test so I'm not worried about it. Wasn't sure if I should JIRA this or not. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4043551#...
