>          Issue Type: Improvement
>    Affects Versions: 3.2.1
>         Environment: Version 3.2.1, not DB dependant

> When Hibernate does a fetch join with a property-ref  in a many-to-one, it issues the join SQL query but needs another select to find the associated entity by property-ref.
> It should be able to use the entity fetched in the join instead (maybe this has been done to ensure the unicity of the associated entity, but it introduce a performance issue).
