Description Tibor Zimanyi 2015-07-30 14:34:42 UTC

Description of problem: 

We have probably still some sync issues in ReteOO part of the engine after changes from [1]. Test MultithreadTest.testSlidingTimeWindows from drools community repo failed on NPE with this stack trace [2]. The failure is nondeterministic, so providing a reproducer will take a bit longer than usual.
