Brian, hibernate doc does not say anything about it, but is there a way to configure collections to not be read again and again from db ? Well , this is my understanding from reading the traces I sent you. Of course I mean, if no changes were applied to neither the entity nor the collection, and given that the first read already inserted the collection in the cache.
