Re: [rules-users] RuleBase.removeRule leads to NoClassDefFoundError

Hi. I work with Steinar. As he mentioned upgrading to 5.0 is not an option for us. Now that we have worked around this problem during compilation (by switching off beta node sharing, see https://jira.jboss.org/jira/browse/JBRULES-2098) we are starting to see similiar problem during stateless session execution: java.lang.NoClassDefFoundError: com/telenor/cos/domain/core/productoffer/rules/subscriptiontype/Rule_Required SubscriptionTypes_11084_0 at com.telenor.cos.domain.core.productoffer.rules.subscriptiontype.Rule_RequiredSubscriptionTypes_11084_0Eval0In voker.evaluate(Unknown Source) at org.drools.rule.EvalCondition.isAllowed(EvalCondition.java:77) at org.drools.reteoo.EvalConditionNode.assertTuple(EvalConditionNode.java:148) at org.drools.reteoo.SingleTupleSinkAdapter.propagateAssertTuple(SingleTupleSinkAdapter.java:20) at org.drools.reteoo.JoinNode.assertTuple(JoinNode.java:110) at org.drools.reteoo.SingleTupleSinkAdapter.createAndPropagateAssertTuple(SingleTupleSinkAdapter.java:55) at org.drools.reteoo.LeftInputAdapterNode.assertObject(LeftInputAdapterNode.java:116) 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:299) 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) We are seeing the same thing as during compilation: TupleNodes associated with removed rules seems to have been left orphaned in the rete tree. I have not been able to find a workaround for this. If this has been fixed in 5.0: Does anybody have any pointers or advice that can help us to create a local patch for 4.0.7 for this? Any help would be much appreciated! Kind regards Christian Steinar Haugen wrote: -- View this message in context: http://www.nabble.com/RuleBase.removeRule-leads-to-NoClassDefFoundError-t...
