[rules-users] Error while upgrdaing drools version

Hi folks, I'm using JBoss 5.1.0 GA, Jboss ESB 4.9 and Drool 5.1.0 recently i have tried to upgrade all my entities as below. *jboss-6.1.0.Final, jbossesb-4.11, drools 5.3.1.Final* while i start app server i'm getting below error and still i couldn't trace it. Is it because of compatibility issue or bug? I'm using same drl file as earlier. 19:01:56,634 ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] Error installing to Start: name=jboss.esb.vfs:///I:/c ep/jboss-6.1.0.Final/server/cep/deploy/cep-esb-1.0-SNAPSHOT.esb state=Create: java.lang.VerifyError: (class: lk/dialog/cep/mobile/Rule_ No_such_offer_yetDefaultConsequenceInvoker, method: evaluate signature: (Lorg/drools/spi/KnowledgeHelper;Lorg/drools/WorkingMemory;)V) Expecting to find integer on stack at java.lang.Class.getDeclaredConstructors0(Native Method) [:1.6.0] at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389) [:1.6.0] at java.lang.Class.getConstructor0(Class.java:2699) [:1.6.0] at java.lang.Class.newInstance0(Class.java:326) [:1.6.0] at java.lang.Class.newInstance(Class.java:308) [:1.6.0] at org.drools.rule.JavaDialectRuntimeData.wire(JavaDialectRuntimeData.java:409) [:5.3.1.Final] at org.drools.rule.JavaDialectRuntimeData.wire(JavaDialectRuntimeData.java:396) [:5.3.1.Final] at org.drools.rule.JavaDialectRuntimeData.onBeforeExecute(JavaDialectRuntimeData.java:237) [:5.3.1.Final] at org.drools.rule.DialectRuntimeRegistry.onBeforeExecute(DialectRuntimeRegistry.java:132) [:5.3.1.Final] at org.drools.compiler.PackageBuilder.reloadAll(PackageBuilder.java:875) [:5.3.1.Final] at org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:828) [:5.3.1.Final] at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:404) [:5.3.1.Final] at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:586) [:5.3.1.Final] at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:37) [:5.3.1.Final] at org.drools.agent.impl.KnowledgeAgentImpl.createPackageFromResource(KnowledgeAgentImpl.java:712) [:5.3.1.Final] at org.drools.agent.impl.KnowledgeAgentImpl.incrementalBuildResources(KnowledgeAgentImpl.java:917) [:5.3.1.Final] at org.drools.agent.impl.KnowledgeAgentImpl.buildKnowledgeBase(KnowledgeAgentImpl.java:659) [:5.3.1.Final] at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:190) [:5.3.1.Final] at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:169) [:5.3.1.Final] at lk.dialog.charging.cep.StatefullCepEngineSingleton.init(StatefullCepEngineSingleton.java:805) [:] at lk.dialog.charging.cep.StatefullCepEngineSingleton.<init>(StatefullCepEngineSingleton.java:83) [:] at lk.dialog.charging.cep.StatefullCepEngineSingleton.intialize(StatefullCepEngineSingleton.java:152) [:] at lk.dialog.charging.cep.feeders.StatefullINUDPVoiceEventFeeder.initialise(StatefullINUDPVoiceEventFeeder.java:30) at org.jboss.soa.esb.listeners.message.ActionProcessingPipeline.initialise(ActionProcessingPipeline.java:397) [:] at org.jboss.soa.esb.listeners.message.MessageAwareListener.doInitialise(MessageAwareListener.java:188) [:] at org.jboss.soa.esb.listeners.lifecycle.AbstractManagedLifecycle.initialise(AbstractManagedLifecycle.java:133) [:] at org.jboss.soa.esb.listeners.lifecycle.ManagedLifecycleController.initialiseInstances(ManagedLifecycleController.java:109) [: ] kind regards Mohan -- View this message in context: http://drools.46999.n3.nabble.com/Error-while-upgrdaing-drools-version-tp...
