LazyInitializationException when "ordered_inserts=true"

When "hibernate.order_inserts = true" and there is an entity been inserted with uninitialized associations it can result in a LazyInitializationException. As I could debug it happens in ActionQueue.findBatchNumber when it tries to find the batch number for an association resulting in a call to the entity hashCode method.

Maybe you could check if the association is initialized before trying to compute its batch number.
