[Regression in 5.2.0.M2]: NPE during rule evaluation on MVELPredicateExpression.evaluate(MVELPredicateExpression.java:82) ------------------------------------------------------------------------------------------------------------------------- Key: JBRULES-2981 URL: https://issues.jboss.org/browse/JBRULES-2981 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core (expert) Affects Versions: 5.2.0.M2 Environment: <properties> <drools.version>5.2.0.M2</drools.version> <drools.planner.version>5.2.0.M2</drools.planner.version> </properties> <dependency> <groupId>org.drools</groupId> <artifactId>drools-core</artifactId> <version>${drools.version}</version> </dependency> <dependency> <groupId>org.drools</groupId> <artifactId>knowledge-api</artifactId> <version>${drools.version}</version> </dependency> <dependency> <groupId>org.drools.planner</groupId> <artifactId>drools-planner-core</artifactId> <version>${drools.planner.version}</version> </dependency> Reporter: Roman Novak Assignee: Edson Tirelli Priority: Critical Fix For: 5.2.0.CR1 The following Rule worked in Version 5.2.0.M1 of drools-core and drools-api. It fails with NPE (s. details below) in Version 5.2.0.M2 of drools-core and knowledge-api. Tested with drools-planner-core 5.1.0 and 5.2.0.M2 => both work. Dialect in DRL file is "java". import org.joda.time.Interval; public class MediumBookingOpt implements Serializable { private static final long serialVersionUID = 5616820300463695243L; private Long mediId; private Interval timeInterval; ... DRL FILE: ... dialect "java" ... query "queryMediumBookingExistsAfter" $mbo1: MediumBookingOpt (); not MediumBookingOpt( mediId == $mbo1.mediId, eval(timeInterval.isAfter($mbo1.getTimeInterval())) )
