Geoffrey De Smet resolved JBRULES-2043.
---------------------------------------

    Fix Version/s: 5.0.0.GA
       Resolution: Done


If you mean your scoreDrl didn't point to a correct classpath resource,
I've tested that out on the latest version and now you get a decent message:

Exception in thread "main" java.lang.IllegalArgumentException: scoreDrl (/org/drools/solver/examples/travelingtournament/solver/smart/ggsmartTravelingTournamentScoreRules.drl) does not exist as a classpath resource.

> After debugging into this location, I found out that it comes from an error in my scoreDrl.
