[ https://issues.jboss.org/browse/DROOLS-469?page=com.atlassian.jira.plugin... ] Lajos Incze edited comment on DROOLS-469 at 4/30/14 10:31 PM: -------------------------------------------------------------- I experience the very same issue, but with enum class, not joda time. The error occurs randomly, the test sometimes runs, sometime fails with this error. I allways use mvn clean test the test inserts 2 test facts (defined by constants) into an empty stateful knowledge session, and a result fact should be inserted when the rule fires. The error: --- testSuccessfulCommissionCalculation(hu.f400.scoring.CommissionCalculationTest) Time elapsed: 0.01 sec <<< ERROR! java.lang.NoSuchMethodError: hu.f400.scoring.rules.facts.Types.<init>(Ljava/lang/String;)V at ConditionEvaluatorb5a0186943d94105a8e9f6ca7550bc45.evaluate(Unknown Source) at org.drools.core.rule.constraint.MvelConstraint.evaluate(MvelConstraint.java:217) at org.drools.core.rule.constraint.MvelConstraint.isAllowed(MvelConstraint.java:174) at org.drools.core.reteoo.AlphaNode.assertObject(AlphaNode.java:134) at org.drools.core.reteoo.CompositeObjectSinkAdapter.doPropagateAssertObject(CompositeObjectSinkAdapter.java:502) at org.drools.core.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:387) at org.drools.core.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:288) at org.drools.core.reteoo.EntryPointNode.assertObject(EntryPointNode.java:260) at org.drools.core.common.NamedEntryPoint.insert(NamedEntryPoint.java:360) at org.drools.core.common.NamedEntryPoint.insert(NamedEntryPoint.java:279) at org.drools.core.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:1148) at org.drools.core.base.DefaultKnowledgeHelper.insert(DefaultKnowledgeHelper.java:223) at org.drools.core.base.DefaultKnowledgeHelper.insert(DefaultKnowledgeHelper.java:217) at hu.f400.scoring.rules.Rule_Calculate_commission282155362.defaultConsequence(Rule_Calculate_commission282155362.java:8) at hu.f400.scoring.rules.Rule_Calculate_commission282155362DefaultConsequenceInvokerGenerated.evaluate(Unknown Source) at hu.f400.scoring.rules.Rule_Calculate_commission282155362DefaultConsequenceInvoker.evaluate(Unknown Source) at org.drools.core.common.DefaultAgenda.fireActivation(DefaultAgenda.java:1016) at org.drools.core.phreak.RuleExecutor.fire(RuleExecutor.java:128) at org.drools.core.phreak.RuleExecutor.evaluateNetworkAndFire(RuleExecutor.java:70) at org.drools.core.common.DefaultAgenda.fireNextItem(DefaultAgenda.java:935) at org.drools.core.common.DefaultAgenda.fireAllRules(DefaultAgenda.java:1200) at org.drools.core.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:957) at org.drools.core.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:931) at org.drools.core.impl.StatefulKnowledgeSessionImpl.fireAllRules(StatefulKnowledgeSessionImpl.java:256) at hu.f400.scoring.CommissionCalculationTest.testSuccessfulCommissionCalculation(CommissionCalculationTest.java:90) --- The Types class, is an bare public enum (constants to name things), nothing special, sg. like below, and is used at LHS matching predicates with == operator when testing equality.
