EvaluatedExpression not well resolved with JIT during race ------------------------------------------------------------ Key: DROOLS-4089 URL: https://issues.jboss.org/browse/DROOLS-4089 Project: Drools Issue Type: Bug Reporter: vincent palau Assignee: Mario Fusco Priority: Major Attachments: debugging-1.png we recently moved from Drools 7.9.0 to 7.20. Some errors started appearing in ours tests when calling static methods in drools. This started happening when all tests were run simultaneously. It seems the mvel JIT compiler kicks in and it incorrectly evaluates the property name: A simple call to {noformat}ValidationUtils.isNullOrEmpty(interestedPartyNumber){noformat} ends up with this kind of error: {noformat} "java.lang.RuntimeException: Unknown property 'nullOrEmpty' on class tech.stage.utils.cwr.model.PublisherRecord" {noformat}
