Issue in Drools 4.0.7 when run in Multithreaded environment ----------------------------------------------------------- Key: JBRULES-1751 URL: https://jira.jboss.org/jira/browse/JBRULES-1751 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 4.0.7 Environment: OS AIX 1.5 Reporter: Sitaraman Balaraman Assignee: Mark Proctor Hi We have a batch program(Informatica mapping) which uses Jars taken from an application which uses JBoss Drools 4.0.7 and MVEL 1.3.7. The informatica Integration service runs in AIX Machine with JRE Version 1.5. The batch program process millions of records which in turn calls the Drools API. To improve the performance, we tried running our informatica process in a multi threaded environment(4 threads). While running we got the following exception for every record that we process(across all the threads). : Exception executing predicate eval( $terDate.before(ExtDateTimeUtils.getDate("01/01/1900")) ) at org.drools.rule.PredicateConstraint.isAllowed(PredicateConstraint.java:216) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:137) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:318) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:145) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:318) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:162) at org.drools.reteoo.Rete.assertObject(Rete.java:175) at org.drools.reteoo.ReteooRuleBase.assertObject(ReteooRuleBase.java:192) at org.drools.reteoo.ReteooWorkingMemory.doInsert(ReteooWorkingMemory.java:71) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:911) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:883) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:684) at org.drools.reteoo.ReteooStatelessSession.execute(ReteooStatelessSession.java:160) at com.wellpoint.eps.epds.business.framework.rules.jbrules.JBRulesExecutor.fireAllRules(JBRulesExecutor.java:85) at com.wellpoint.eps.epds.business.framework.validation.BaseHandlerImpl.validateInternal(BaseHandlerImpl.java:141) at com.wellpoint.eps.epds.business.framework.validation.BaseHandlerImpl.validateInternal(BaseHandlerImpl.java:75) at com.wellpoint.eps.epds.business.framework.validation.AbstractBusinessRuleHandler.validate(AbstractBusinessRuleHandler.java:43) at com.wellpoint.eps.epds.business.application.validation.ProviderContractBusinessRuleHandler.validate(ProviderContractBusinessRuleHandler.java:43) at com.wellpoint.eps.epds.business.framework.service.DefaultRuleValidationServiceImpl.applyBusinessRules(DefaultRuleValidationServiceImpl.java:284) at com.eps.epds.api.validation.ValidationServiceDeligator$DefaultValidationServiceImpl.validate(ValidationServiceDeligator.java:181) at com.informatica.powercenter.server.jtx.JTXPartitionDriverImplGen.inputTransaction(JTXPartitionDriverImplGen.java:1414) Caused by: org.mvel.CompileException: cannot invoke method at org.mvel.optimizers.impl.refl.MethodAccessor.getValue(MethodAccessor.java:54) at org.mvel.optimizers.impl.refl.VariableAccessor.getValue(VariableAccessor.java:39) at org.mvel.ast.VariableDeepPropertyNode.getReducedValueAccelerated(VariableDeepPropertyNode.java:22) at org.mvel.ast.PropertyASTNode.getReducedValueAccelerated(PropertyASTNode.java:21) at org.mvel.MVELRuntime.execute(MVELRuntime.java:90) at org.mvel.CompiledExpression.getValue(CompiledExpression.java:111) at org.mvel.MVEL.executeExpression(MVEL.java:235) at org.drools.base.mvel.MVELPredicateExpression.evaluate(MVELPredicateExpression.java:45) at org.drools.rule.PredicateConstraint.isAllowed(PredicateConstraint.java:209) ... 20 more Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.GeneratedMethodAccessor45.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:615) at org.mvel.optimizers.impl.refl.MethodAccessor.getValue(MethodAccessor.java:46) ... 28 more Caused by: java.lang.NullPointerException at java.util.Date.getMillisOf(Date.java:953) at java.util.Date.before(Date.java:912) ... 32 more ].
