NPE in PackageBuilderContext for mvel related code -------------------------------------------------- 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.CR1 On jenkins drools often craches on this line in PackageBuildContext: {code} this.typesafe = ((MVELDialect) dialectRegistry.getDialect( "mvel" )).isStrictMode(); {code} This happens in the optaplanner and optaplanner-runTurtleTests jobs.
