> i have 2 very simple rules and a test case (see attached maven project).
> trying to set MultithreadEvaluationOption.YES on the KB causes the test to fail sporadically (~10% of the times?).
> the attached project contains a testsuite that runs the same test 8 times (testsuite is defined in RunMe.java). attempting "mvn clean install" runs this suite and usually fails.
> commenting out the MultithreadEvaluationOption.YES line in the other testcase (the one referred-to from RunMe) causes the tests to behave as expected (pass).
