Enable specifying the fetch mode for map-key-many-to-many and index-many-to-many
--------------------------------------------------------------------------------

                 Key: HHH-5924
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5924
             Project: Hibernate Core
          Issue Type: New Feature
          Components: core
    Affects Versions: 3.6.1
         Environment: doesn't matter
            Reporter: Robert Wruck


The documentation says that with many-to-many "... for full eager fetching in a single SELECT  of an entity and its many-to-many relationships to other entities, you would enable join fetching,not only of the collection itself, but also with this attribute on the <many-to-many>  nested element".

This seems to also apply to map-key-many-to-many and index-many-to-many where the default setup generates 1+N SELECTs. Unfortunately the DTD (and maybe hibernate itself) currently doesn't support specifying fetch="join" for these elements.
