org.hibernate.engine.EntityEntry
We need an entry to tell us all about the current state of an object with respect to its persistent state @author Gavin King

    Object existing = persistenceContext.getEntity( keyToLoad );
    if ( existing != null ) {

        EntityEntry entry = persistenceContext.getEntry( existing );
        Status status = entry.getStatus();
        if ( status == Status.DELETED || status == Status.GONE ) {
          return null;
