Gail Badner resolved HHH-5813.
------------------------------

      Assignee: Gail Badner
    Resolution: Rejected

uniqueResult() is intended to remove duplicate objects. It is not intended to remove equal objects.

>From the documentation:

The uniqueResult() method offers a shortcut if you know your query will only return a single object. Queries that make use of eager fetching of collections usually return duplicates of the root objects, but with their collections initialized.
