Got EntityExistsException when invoking EntityManager.merge() to persist a new entity bean
with generated id  and enhanced at deployment time 
----------------------------------------------------------------------------------------------------------------------------------------------

                 Key: OPENJPA-585
                 URL: https://issues.apache.org/jira/browse/OPENJPA-585
             Project: OpenJPA
          Issue Type: Bug
          Components: kernel
    Affects Versions: 1.1.0
            Reporter: Jason Zheng


I create a new entity object with generated id, enhance it at deployment time and persist
it into db by invoking EntityManager.merge().
Department d = new Department();
d.setName('qa');
pc.merge(d);

Got below exception,
<openjpa-1.1.0-SNAPSHOT-r422266:647033 nonfatal store error> org.apache.openjpa.persistence.EntityExistsException:
Attempt to persist detached object 'org.apache.openjpa.enhance.tests$functional$jee$misc$classredefinition$common$apps$appforredefinition$entity$Department$pcsubclass@acb905'.
If this is a new instance, make sure any versino and/or auto-generated primary key fields
are null/default when persisting.

This is caused by a bug in VersionAttachStrategy, which creates appId and passes it to persist()
call for a new entity whose id is annotated with @GeneratedValue.
