             Summary: NPE 
                 Key: DROOLS-103
                 URL: https://issues.jboss.org/browse/DROOLS-103
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
            Reporter: Geoffrey De Smet
            Assignee: Mario Fusco
             Fix For: 6.0.0.Beta2


On jenkins drools often craches on this line in PackageBuildContext:
this.typesafe = ((MVELDialect) dialectRegistry.getDialect( "mvel" )).isStrictMode();


This happens in the optaplanner and optaplanner-runTurtleTests jobs.
Locally I haven't seen it yet.
