Mario Fusco commented on DROOLS-1471:
-------------------------------------

Sorry but it is impossible for me to investigate and eventually fix this issue without a reproducer. Can you please provide one?
Also there's a chance that this issue has been already solved in drools 6.5. Did you give it a try?
