[jboss-jira] [JBoss JIRA] (DROOLS-4089) EvaluatedExpression not well resolved with JIT during race

EvaluatedExpression not well resolved with JIT during race ------------------------------------------------------------ Key: DROOLS-4089 URL: https://issues.jboss.org/browse/DROOLS-4089 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 7.20.0.Final, 7.22.0.Final 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 LHS 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} Debugging info: Related source-code: https://github.com/kiegroup/drools/blob/7.20.0.Final/drools-core/src/main... !debugging-1.png|full! 1) is the current evaluated property 2) Should be the right property of WriterRecord 3) Perhaps the expression which should be executed instead of invocations.get(0) We fixed that somehow disabling JIT with {noformat}ConstraintJittingThresholdOption{noformat} Is there any chance to this bug fixed? Do you need more info? Thanks in advance for your support. {panel:title=Reproducer} https://github.com/vp-stage/evaluatedexpressionandjit {panel}
