Re: [rules-users] java.lang.ArrayIndexOutOfBoundsException thrown in mvel2's compiler when running drools5.3 final.

hi all, the exception below is usually thrown when the system is busy(usually 9-10 am everyday); The rules runs perfectly when unit test or any other time when the system is not very busy(like 22:00 - 4:00 every day); Our system processes 13000000 pieces of data each day, with 4-5 java.lang.ArrayIndexOutOfBoundsException thrown on average.It's not very often but doubtful. The logs are shown below: 2012-03-07 10:10:33,683 [] ERROR ruleservice.RuleServiceImpl - Error occurred while invoking business filter! java.lang.reflect.InvocationTargetException at com.alibaba.china.avatar.offer.rulematch.OfferMatchFilter$$FastClassByCGLIB$$18f6f037.invoke(<generated>) at net.sf.cglib.reflect.FastMethod.invoke(FastMethod.java:53) at com.alibaba.china.ruleservice.RuleServiceImpl.bindParamAndInvoke(RuleServiceImpl.java:264) at com.alibaba.china.ruleservice.RuleServiceImpl.match(RuleServiceImpl.java:82) at sun.reflect.GeneratedMethodAccessor248.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:310) at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:182) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:149) at com.alibaba.china.avatar.interceptor.KeyDataLoggingAfterThrowingInterceptor.invoke(KeyDataLoggingAfterThrowingInterceptor.java:24) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:171) at com.alibaba.dragoon.patrol.spring.DragoonMethodInterceptor.invoke(DragoonMethodInterceptor.java:106) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:171) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:204) at $Proxy16.match(Unknown Source) at com.alibaba.china.avatar.offer.decode.OfferMessageAction.run(OfferMessageAction.java:39) at com.alibaba.china.rialto.core.module.DefaultActionModule.doWork(DefaultActionModule.java:375) at com.alibaba.china.rialto.core.module.DefaultActionModule.runModule(DefaultActionModule.java:252) at com.alibaba.china.rialto.core.module.ModuleRunner.run(ModuleRunner.java:31) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) Caused by: org.drools.RuntimeDroolsException: Exception executing predicate Helper.containsAny(offerSubject, ((Set)colMap.get("_set_212"))) at org.drools.rule.PredicateConstraint.isAllowed(PredicateConstraint.java:298) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:130) at org.drools.reteoo.CompositeObjectSinkAdapter.doPropagateAssertObject(CompositeObjectSinkAdapter.java:458) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:386) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:215) at org.drools.reteoo.EntryPointNode.assertObject(EntryPointNode.java:244) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:330) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:291) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:886) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:845) at org.drools.impl.StatefulKnowledgeSessionImpl.insert(StatefulKnowledgeSessionImpl.java:255) at com.alibaba.china.ruleservice.session.impl.drools5.TransientDrools5Session.insertFact(TransientDrools5Session.java:100) at com.alibaba.china.avatar.offer.rulematch.OfferMatchFilter.doFilter(OfferMatchFilter.java:57) ... 23 more Caused by: [Error: unexpected end of statement] [Near : {...

And every ArrayIndexOutOfBoundsException is thrown around here:  'Helper.containsAny(offerSubject, ((Set)colMap.get("_set_212")))' .This is a custom static function call which implements come sort of operation not supported by drools5. Is this a bug about mvel2?Or any one encountered this problem also? How could I avoid it? Thnaks! -- Regards. Miles.
