Duplicate object in persistent bag - regression in 3.3.1 EM
-----------------------------------------------------------

                 Key: EJB-314
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-314
             Project: Hibernate Entity Manager
          Issue Type: Bug
          Components: EntityManager
    Affects Versions: 3.3.1.GA, 3.2.1
         Environment: Hibernate version: 3.2.2
Hibernate annotations version: 3.3.0
Hibernate em version: 3.3.1 
hsqldb 1.8.0 
            Reporter: Vincent Sevel
         Attachments: sources.txt, test_code_between_open_close.txt

Doing a persist on a new object that has been added to an unitialized persistent bag, with lead to this collection containing 2 times the same new instance.

However, if the collection is forced to be initialized before the persist, then it behaves correctly. 

This was working in 3.2.1, not anymore in 3.3.1.

Look at the method findOrCreateCustodianAccount in test_code_between_open_close.txt and the XXX comments.
