Merging lazy bidirectional one-to-one association with CascadeType.MERGE from both sides does not work correctly.
-----------------------------------------------------------------------------------------------------------------

                 Key: HHH-3714
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3714
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.3.1
         Environment: Hibernate Core 	 3.3.1.GA
Hibernate Annotations 	3.4.0 GA
Hibernate EntityManager 	3.4.0 GA
Hibernate Validator 	3.1.0 GA
            Reporter: Tihomir Totev
         Attachments: merge_bug.zip

If you merge in the session object that has mappedBy annotation it works fine, but when you merge the other object it is inserted twice in the database. Then "More than one row with the given identifier was found" is given, which is correct since it is really inserted twice.

I'm attaching a test of this problem.

This test was working fine with core 3.2.6.ga.
