Regression for "special DRL operator" matches on 6.2.0.Final ------------------------------------------------------------ Key: DROOLS-856 URL: https://issues.jboss.org/browse/DROOLS-856 Project: Drools Issue Type: Bug Affects Versions: 6.2.0.Final Environment: Works fine on 6.1.0.Final, but breaks at runtime with 6.2.0.Final - compilation with 6.2.0.Final is OK, just runtime breaks Reporter: Matteo Mortari Assignee: Mark Proctor Attachments: 20150723.DROOLS-856.exercise-matches620f..zip This is affecting at least the {{matches}} operator but could it also have further impacts, up to you to evaluate =) I hope is helpful case. I will attach reproducer. Assume the following rules : {code} rule "color measure wrap" salience 1000 no-loop when $m : Measurement( id == "color" ) then AWrapper aw = new AWrapper($m); retract($m); insert(aw); end rule "wrapper matches" salience 999 no-loop when AWrapper ( $val : m.dataVal() , $val matches "#......" ) then System.out.println("I've matched an actual color, "+$val); end {code} This passes the rule-compilation stage OK on both 6.1.0.Final and 6.2.0.Final of the kie-maven-plugin for instance, but breaks at runtime with 6.2.0.Final with the following stacktrace: {code} [INFO] --- kie-maven-plugin:6.2.0.Final:build (default-build) @ exercise-matches620f --- [INFO] Adding KieModule from resource: FileResource[file=C:\eclipse44sr2\workspace-puredrools\exercise-matches620F\exercise-matches620f\src\main\resources] [WARNING] Unable to find pom.properties in /C:/eclipse44sr2/workspace-puredrools/exercise-matches620F/exercise-matches620f/src/main/resources [INFO] Recursed up folders, found and used pom.xml C:\eclipse44sr2\workspace-puredrools\exercise-matches620F\exercise-matches620f\pom.xml [INFO] KieModule was added: FileKieModule[releaseId=com.acme:exercise-matches620f:0.0.1-SNAPSHOT,file=C:\eclipse44sr2\workspace-puredrools\exercise-matches620F\exercise-matches620f\src\main\resources] [INFO] KieModule successfully built!
