---------------------------------

Hi,

The following is a simple hack to disable Hibernate's duplicate association check:

Change JoinWalker.isDuplicateAssociation(String, String[]) to always return false.

Note that this may cause any program with a mapping which has a non-lazy circular association to loop forever if there is a cycle in the object graph. For my research purposes this was fine because I never have non-lazy associations. Running Hibernate's unit tests, none of them actually loops forever and as I remember only a couple more unit tests fail mainly due to them expecting an association to be lazy when it isn't.
