Description Mario Fusco 2013-11-12 19:36:39 UTC 
Reproducer at: https://github.com/DuncanDoyle/DroolsInOrderTemporalReasoningPhreakLoopAndHang

Clone the project in the given GitHub repository and run 'mvn -Pphreak clean test' (-Pphreak runs the test with PHREAK, -Preteoo runs the test with ReteOO).

ReteOO works fine, but PHREAK goes into an infinite-loop. Setting 'no-loop' on the "TECH-rule-RG-FLT-03B Retract all filtered events once we've sent an event."-rule causes the engine to hang and use 100% CPU on one core.
