> 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.
