I am dynamically adding/modifying rules (packages) to a loaded rule-base and having issues specifically when my rule contains accumulate CE. For an example, following is a rule which I am trying to add to my rulebase (which is already loaded in memory). rule "7d7fa7f1-164b-45a7-8e5a-c0c260815f9a" enabled true salience 0 no-loop true agenda-group "DATA_ARRIVAL" when AgentID(agentId : agentId); DeviceData() Property(key=="threshold",classifier=="7d7fa7f1-164b-45a7-8e5a-c0c260815f9a.Condition0",$prop_threshold0 : value) $total0: Number( doubleValue > $prop_threshold0) from accumulate( DataPoint( $value0: value ) from dataService.getDataPoints("5e0de623-9a25-45a1-8bc5-745254c2576e","SPEED",3), average( $value0) ) then agent.handleAction("rules.sl.7d7fa7f1-164b-45a7-8e5a-c0c260815f9a",0); end I am not getting any error (Rule validation or any other) when adding package with my rule to rulebase, but when getting following error, when rulebase is used thereafter: java.lang.NoClassDefFoundError: rules/sl/Rule_7d7fa7f1_164b_45a7_8e5a_c0c260815f9a_0 at rules.sl.Rule_7d7fa7f1_164b_45a7_8e5a_c0c260815f9a_0AccumulateExpression0Invoker.evaluate(Unknown Source) at org.drools.base.accumulators.JavaAccumulatorFunctionExecutor.reverse(JavaAccumulatorFunctionExecutor.java:91) at org.drools.rule.Accumulate.reverse(Accumulate.java:151) at org.drools.reteoo.AccumulateNode.modifyTuple(AccumulateNode.java:376) at org.drools.reteoo.AccumulateNode.retractObject(AccumulateNode.java:292) at org.drools.reteoo.SingleObjectSinkAdapter.propagateRetractObject(SingleObjectSinkAdapter.java:32) at org.drools.reteoo.RightInputAdapterNode.retractTuple(RightInputAdapterNode.java:124) at org.drools.reteoo.SingleTupleSinkAdapter.propagateRetractTuple(SingleTupleSinkAdapter.java:38) at org.drools.reteoo.FromNode.retractTuple(FromNode.java:130) at org.drools.reteoo.CompositeTupleSinkAdapter.propagateRetractTuple(CompositeTupleSinkAdapter.java:52) at org.drools.reteoo.JoinNode.retractTuple(JoinNode.java:231) at org.drools.reteoo.CompositeTupleSinkAdapter.propagateRetractTuple(CompositeTupleSinkAdapter.java:52) at org.drools.reteoo.JoinNode.retractObject(JoinNode.java:191) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateRetractObject(CompositeObjectSinkAdapter.java:375) at org.drools.reteoo.ObjectTypeNode.retractObject(ObjectTypeNode.java:189) at org.drools.reteoo.Rete.retractObject(Rete.java:215) at org.drools.reteoo.ReteooRuleBase.retractObject(ReteooRuleBase.java:211) at org.drools.reteoo.ReteooWorkingMemory.doRetract(ReteooWorkingMemory.java:79) at org.drools.common.AbstractWorkingMemory.retract(AbstractWorkingMemory.java:1023) at org.drools.common.AbstractWorkingMemory.retract(AbstractWorkingMemory.java:982) at com.sensorlogic.rules.RuleAgent.retractMatchingFact(RuleAgent.java:283) at com.sensorlogic.rules.RuleAgent.processFact(RuleAgent.java:264) at com.sensorlogic.rules.RuleAgent.run(RuleAgent.java:342) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:650) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:675) at java.lang.Thread.run(Thread.java:595) I will appreciate any insight with this problem.

Yes, I just updated to 4.0.7 before couple of days. But I tried it out with 4.0.4 also with same results. So I don't think this is something introduced in 4.0.7, but not sure.
