                 Key: DROOLS-518
                 URL: https://issues.jboss.org/browse/DROOLS-518
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 6.1.0.Beta4, 6.0.1.Final, 6.0.0.Final
         Environment: Windows;Java1.7.0_55,Drools 6.0.0.Final through 6.1.0.Beta4
            Reporter: Thomas Mogwitz
            Assignee: Mark Proctor


Upon porting Drools-relating code in our product from 5.5.0 to 6.0.1, I found that one unit test accompanying a rule set failed with an NullPointerException.
After quite a while of debugging in the innards of the rule engine I am quite that I didn't make a mistake in porting to Drools 6.0.1 but this is rather a
bug in the rule engine. Seems to me like there's something going wrong while cleaning up the working memory after firing a rule.
