Problems when using auto incrementing colums that start at zero 
----------------------------------------------------------------

                 Key: OPENJPA-1665
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1665
             Project: OpenJPA
          Issue Type: Bug
    Affects Versions: 2.0.0
            Reporter: Rick Curtis
            Assignee: Rick Curtis


This issue was reported on the users mailing list[1].

The issue is that it is possible when using auto generated ids that there is a current entity
in the persistence context that has an id of zero, and by default when a new entity is created
it also has an id of zero. When persisting the second entity, OpenJPA incorrectly detects
that there are multiple entities with the same id in the context even though the new id doesn't
have an id from the database yet.
