---------------------------------------------------------------------------------------------------
Key: OPENJPA-330

Project: OpenJPA
Issue Type: Bug
Components: jpa
Affects Versions: 1.0.0
Reporter: Henry Lai
unable to persist a new entity, when there is a entity with id value 0 loaded in persistent context.
The entity is declared to use generated value sequence strategy.
<1.0.0-SNAPSHOT-SNAPSHOT nonfatal store error> org.apache.openjpa.persistence.EntityExistsException: An object of type "ptp.test.issue7.T7Entity" with oid "ptp.test.issue7.T7Entity-0" already exists in this context; another cannot be persisted.
public void testEntityWithZeroID(){
PersistenceProviderImpl openJPA = new PersistenceProviderImpl();
EntityManagerFactory factory =
openJPA.createEntityManagerFactory("test", "ptp/test/issue7/persistence.xml",
System.getProperties() );
EntityManager em = factory.createEntityManager();
em.getTransaction().begin();
Query deleteStmt = em.createNativeQuery("delete from T7Entity");
deleteStmt.executeUpdate();
em.getTransaction().commit();
em = factory.createEntityManager();
em.getTransaction().begin();
Query createStmt = em.createNativeQuery("insert into T7Entity (S_ID,NAME) values (0,'MICKEY')");
createStmt.executeUpdate();
em.getTransaction().commit();
em = factory.createEntityManager();
em.getTransaction().begin();
Query query = em.createQuery("select obj from T7Entity obj");
List resultList = query.getResultList();
T7Entity aEntity = new T7Entity();
aEntity.setName("Minnie");
em.persist(aEntity); // fails here
em.getTransaction().commit();
em.close();
