[jboss-jira] [JBoss JIRA] (JBRULES-3622) Improve the error message for the ClassCastException when Using interval-based Temporal Operators with timestamps

Improve the error message for the ClassCastException when Using interval-based Temporal Operators with timestamps ----------------------------------------------------------------------------------------------------------------- Key: JBRULES-3622 URL: https://issues.jboss.org/browse/JBRULES-3622 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core (expert) Affects Versions: 5.4.0.Final Environment: Mac OSX 10.6.8, Java 6 Reporter: Julian Klein Assignee: Mark Proctor Priority: Minor When trying to determine if two dates overlap using the "overlappedby" keyword with parameters in a rule, Drools throws a ClassCastException. If I use another temporal keyword such as "coincides" with parameters, the rule works as expected. I am using a StatefulKnowledgeSession and this occurs after I insert facts into the session. The facts I insert are of a different type than TimeBoxedFact. The LHS is as follows: {code} $encD : TimeBoxedFact(yearRecorded == durationCycleYear ) $encN : TimeBoxedFact( ID != $encD.ID, datetimeRecorded overlappedby[1ms,90d] $encD.datetimeRecorded ) {code} durationCycleYear is a global Integer equal to the four digit year (e.g. 2012 or 1998; declared as follows "global Integer durationCycleYear;") Here is what the TimeBoxedFact object looks like: {code} package com.company; import java.io.Serializable; import java.sql.Timestamp; public class TimeBoxedFact implements Serializable{ protected Timestamp datetime = null; protected int ID; private static final long serialVersionUID = -7640003804511140444L; public int getID() { return this.ID; } public void setID(int id) { this.ID = id; } public Timestamp getDatetimeRecorded() { return this.datetime; } public java.util.Date getDateRecorded(){ return new java.util.Date(this.datetime.getTime()); } public int getYearRecorded(){ return calendarDateRecorded.get(Calendar.YEAR); } public void setDatetimeRecorded(Timestamp dt) { this.datetime = dt; //create the calendar object calendarDateRecorded = Calendar.getInstance(); calendarDateRecorded.setTimeInMillis(datetime.getTime()); } } {code} The stack trace is as follows: {code} java.lang.ClassCastException: org.drools.common.DefaultFactHandle cannot be cast to com.company.TimeBoxedFact at org.drools.base.com.company.TimeBoxedFact1639733674$getDatetimeRecorded.getValue(Unknown Source) at org.drools.base.extractors.BaseObjectClassFieldReader.isNullValue(BaseObjectClassFieldReader.java:179) at org.drools.base.ClassFieldReader.isNullValue(ClassFieldReader.java:179) at org.drools.rule.VariableRestriction$ObjectVariableContextEntry.updateFromTuple(VariableRestriction.java:327) at org.drools.common.DoubleBetaConstraints.updateFromTuple(DoubleBetaConstraints.java:137) at org.drools.reteoo.JoinNode.assertLeftTuple(JoinNode.java:84) at org.drools.reteoo.SingleLeftTupleSinkAdapter.doPropagateAssertLeftTuple(SingleLeftTupleSinkAdapter.java:196) at org.drools.reteoo.SingleLeftTupleSinkAdapter.propagateAssertLeftTuple(SingleLeftTupleSinkAdapter.java:71) at org.drools.reteoo.JoinNode.assertLeftTuple(JoinNode.java:98) at org.drools.reteoo.SingleLeftTupleSinkAdapter.doPropagateAssertLeftTuple(SingleLeftTupleSinkAdapter.java:196) at org.drools.reteoo.SingleLeftTupleSinkAdapter.createAndPropagateAssertLeftTuple(SingleLeftTupleSinkAdapter.java:145) at org.drools.reteoo.LeftInputAdapterNode.assertObject(LeftInputAdapterNode.java:154) at org.drools.reteoo.CompositeObjectSinkAdapter.doPropagateAssertObject(CompositeObjectSinkAdapter.java:497) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:382) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:364) 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:337) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:298) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:888) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:847) at org.drools.impl.StatefulKnowledgeSessionImpl.insert(StatefulKnowledgeSessionImpl.java:269) at com.company.RulesRunner.persistAndInsertBRE(RulesRunner.java:267) at com.company.RulesRunner.runRules(RulesRunner.java:249) at com.company.testProtocol_0_In90Days(Test025.java:205) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:76) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.junit.runner.JUnitCore.run(JUnitCore.java:157) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:76) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:195) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:63) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:120) {code}
