Operators on java.lang.Comparable object doesn't work if JIT is enable ---------------------------------------------------------------------- Key: DROOLS-37 URL: https://issues.jboss.org/browse/DROOLS-37 Project: Drools Issue Type: Bug Affects Versions: 5.5.0.Final Environment: Windows XP Java 1.5 joda-time 1.6.2 Reporter: Jérémy SOULA Assignee: Mario Fusco Labels: 5.5, comparable, localDate Fix For: 5.5.1.Final, 6.0.0.Alpha9 Attachments: drools-bugs.zip In my application, i have rules that used org.joda.time.LocalDate to compare date like {noformat} rule "toto" when LocalDateForDroolsTestBean( infDate>=supDate ) then //Anything end {noformat} With Drools 5.3, all works fine. With Drools 5.5, an exception occured because JIT optimizer automaticaly enabled: {noformat} Exception in thread "main" java.lang.NoSuchMethodError: org.joda.time.LocalDate.compareTo(Lorg/joda/time/LocalDate;)I at ConditionEvaluatorf8ba8fa3003345adbf3979e901488f23.evaluate(Unknown Source) at org.drools.rule.constraint.MvelConstraint.evaluate(MvelConstraint.java:200) at org.drools.rule.constraint.MvelConstraint.isAllowed(MvelConstraint.java:157) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:137) at org.drools.reteoo.SingleObjectSinkAdapter.propagateAssertObject(SingleObjectSinkAdapter.java:59) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:235) at org.drools.reteoo.EntryPointNode.assertObject(EntryPointNode.java:240) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:350) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:311) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:903) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:847) at org.drools.impl.StatefulKnowledgeSessionImpl.insert(StatefulKnowledgeSessionImpl.java:269) at org.drools.impl.StatelessKnowledgeSessionImpl.execute(StatelessKnowledgeSessionImpl.java:304) at fr.jsoula.jboss.drools.bugs.comparable.ComparableBug.main(ComparableBug.java:39) {noformat} After search, it seems that the bytecode generated by org.drools.rule.builder.dialect.asm.ClassGenerator can't call the method public int compareTo(Object partial) of org.joda.time.LocalDate. The parameter of the method must be the same class of the current object.
