Exception while processing 'or' condition ----------------------------------------- Key: DROOLS-4667 URL: https://issues.jboss.org/browse/DROOLS-4667 Project: Drools Issue Type: Bug Affects Versions: 7.0.0.Final, 7.28.0.Final Environment: Unit test in 7.29.0-SNAPSHOT Reporter: Oleg Ermolaev Assignee: Mario Fusco Priority: Major Attachments: ConditionOrTest.java, condition-or-test.txt Depending on the facts being verified, the test produces the following errors: * ArrayIndexOutOfBoundsException; * ClassCastException; * double rule execution. if you replace "A or B" with "!(!A and !B)" than all tests pass successfully. {code:none} java.lang.RuntimeException: java.lang.ArrayIndexOutOfBoundsException: Index 2 out of bounds for length 2 at org.drools.core.rule.MultiAccumulate.accumulate(MultiAccumulate.java:114) at org.drools.core.phreak.PhreakAccumulateNode.addMatch(PhreakAccumulateNode.java:709) at org.drools.core.phreak.PhreakAccumulateNode.doLeftInserts(PhreakAccumulateNode.java:168) at org.drools.core.phreak.PhreakAccumulateNode.doNode(PhreakAccumulateNode.java:89) at org.drools.core.phreak.RuleNetworkEvaluator.switchOnDoBetaNode(RuleNetworkEvaluator.java:581) at org.drools.core.phreak.RuleNetworkEvaluator.evalBetaNode(RuleNetworkEvaluator.java:552) at org.drools.core.phreak.RuleNetworkEvaluator.evalNode(RuleNetworkEvaluator.java:379) at org.drools.core.phreak.RuleNetworkEvaluator.innerEval(RuleNetworkEvaluator.java:339) at org.drools.core.phreak.RuleNetworkEvaluator.evalStackEntry(RuleNetworkEvaluator.java:237) at org.drools.core.phreak.RuleNetworkEvaluator.outerEval(RuleNetworkEvaluator.java:180) at org.drools.core.phreak.RuleNetworkEvaluator.evaluateNetwork(RuleNetworkEvaluator.java:133) at org.drools.core.phreak.RuleExecutor.reEvaluateNetwork(RuleExecutor.java:213) at org.drools.core.phreak.RuleExecutor.evaluateNetworkAndFire(RuleExecutor.java:88) at org.drools.core.concurrent.AbstractRuleEvaluator.internalEvaluateAndFire(AbstractRuleEvaluator.java:34) at org.drools.core.concurrent.SequentialRuleEvaluator.evaluateAndFire(SequentialRuleEvaluator.java:43) at org.drools.core.common.DefaultAgenda.fireLoop(DefaultAgenda.java:1101) at org.drools.core.common.DefaultAgenda.internalFireAllRules(DefaultAgenda.java:1048) at org.drools.core.common.DefaultAgenda.fireAllRules(DefaultAgenda.java:1040) at org.drools.core.impl.StatefulKnowledgeSessionImpl.internalFireAllRules(StatefulKnowledgeSessionImpl.java:1330) at org.drools.core.impl.StatefulKnowledgeSessionImpl.fireAllRules(StatefulKnowledgeSessionImpl.java:1321) at org.drools.core.impl.StatefulKnowledgeSessionImpl.fireAllRules(StatefulKnowledgeSessionImpl.java:1305) at org.drools.compiler.integrationtests.ConditionOrTest.doTest0(ConditionOrTest.java:288) at org.drools.compiler.integrationtests.ConditionOrTest.doTest(ConditionOrTest.java:268) at org.drools.compiler.integrationtests.ConditionOrTest.test_1_01_00(ConditionOrTest.java:123) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:78) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268) at org.junit.runners.ParentRunner.run(ParentRunner.java:363) at org.junit.runner.JUnitCore.run(JUnitCore.java:137) at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68) at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:47) at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:242) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70) Caused by: java.lang.ArrayIndexOutOfBoundsException: Index 2 out of bounds for length 2 at org.drools.core.base.mvel.MVELCompilationUnit.updateFactory(MVELCompilationUnit.java:406) at org.drools.core.base.mvel.MVELCompilationUnit.getFactory(MVELCompilationUnit.java:324) at org.drools.core.base.accumulators.MVELAccumulatorFunctionExecutor.accumulate(MVELAccumulatorFunctionExecutor.java:120) at org.drools.core.rule.MultiAccumulate.accumulate(MultiAccumulate.java:105) ... 45 more {code} {code:none} java.lang.RuntimeException: java.lang.ClassCastException: class org.drools.compiler.integrationtests.ConditionOrTest$Dog cannot be cast to class [Ljava.lang.Object;
