             Summary: MultithreadTest.testSlidingTimeWindows() uses unreliable Thread.sleep(1).
                 Key: DROOLS-748
                 URL: https://issues.jboss.org/browse/DROOLS-748
             Project: Drools
          Issue Type: Bug
            Reporter: Tibor Zimányi
            Assignee: Mark Proctor
            Priority: Minor


In MultithreadTest classes (there are two of them) method testSlidingTimeWindows() uses unreliable Thread.sleep(1) call for waiting for fact insertion. Thread.sleep(1) doesn't wait for exactly 1 millisecond, because there is overhead from thread scheduler. This overhead can be pretty large in contrast to expected 1ms sleep.
