Re: [eclipselink-users] Optimistic Lock Exception expected 
James,
is there any chance that a fix for this is available any time soon?
Thanks,

Looking at the code, the merge() is not throwing an error for versioned
objects that were deleted.  Please log a bug for this and post the id, so I
can also vote for it.

Hi,
Enclosed, you'll find the source code of the entity/main class and log output: 


public class Main {

     private static EntityManagerFactory emf;

     public static void main(String[] args) {
JpaHelper.getServerSession(getEntityManagerFactory()).getProject().assumeExistenceForDoesExist(); 

         SimpleEntity entity = new SimpleEntity();
         entity.setValue("entity");

         //persist "entity" and create clone "entityCopy"
EntityManager em1 = getEntityManagerFactory().createEntityManager(); 
         em1.getTransaction().begin();
         em1.persist(entity);
         em1.getTransaction().commit();
SimpleEntity entityCopy = em1.find(SimpleEntity.class, entity.getId()); 
         em1.close();

         //delete "entity" from database
EntityManager em2 = getEntityManagerFactory().createEntityManager(); 
         em2.getTransaction().begin();
         entity = em2.merge(entity);
         em2.remove(entity);
         em2.getTransaction().commit();
         em2.close();

         //merge clone "entityCopy" and commit
EntityManager em3 = getEntityManagerFactory().createEntityManager(); 
         em3.getTransaction().begin();
         entityCopy = em3.merge(entityCopy);
         em3.lock(entityCopy, LockModeType.WRITE);
         em3.getTransaction().commit();
         em3.close();
     }

     private static EntityManagerFactory getEntityManagerFactory() {
         if (emf == null) {
emf = Persistence.createEntityManagerFactory("EclipseLinkTestPU"); 
         }
         return emf;
     }
