Using @CollectionOfEelements with FetchMode.JOIN and FetchType.EAGER to map a Map breaks Example criteria
---------------------------------------------------------------------------------------------------------

                 Key: ANN-603
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-603
             Project: Hibernate Annotations
          Issue Type: Bug
          Components: search
    Affects Versions: 3.3.0.ga
         Environment: hibernate-core-3.2.2.jar
            Reporter: Philippe Laflamme
         Attachments: ann-example_eager_join.patch

I'm using CollectionOfElements to map a Map<String, @Embeddable>. I want it to eagerly join the associated table to fill the map.

When I load the Entity using its PK, I obtain a single object with multiple entries in the Map, which is the expected behaviour. If I load the same Entity using an Example criteria (matching one of its property), I get one Entity per entry in the Map.

If you use FetchMode.SELECT, the resulting Example query returns a single entity with multiple values in the Map (expected behaviour).

Attached is a patch against annotations_3_3_0_GA that creates a test case in CollectionElementTest that reproduces the problem.
