Natural id lookups cause problems with loading cached owned collections based on a property-ref
-----------------------------------------------------------------------------------------------

                 Key: HHH-5853
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5853
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
            Reporter: Steve Ebersole
            Assignee: Steve Ebersole
             Fix For: 3.6.1
         Attachments: CollectionIssue_TestProgram.zip

See the attached test case for specifics.  

Essentially we have an entity which:
# contains a natural-id definition
# contains a collection, whose key is defined using a property-ref

Trying to perform a lookup by natural id triggers the error.

Workarounds include:
# Not doing the natural id lookup, but opt for the pk lookup.
# removing the property-ref, using the PK as the FK target
