             Summary: ConcurrentModificationException thrown from org.drools.modelcompiler.constraints.LambdaAccumulator.hashCode
                 Key: DROOLS-5043
                 URL: https://issues.redhat.com/browse/DROOLS-5043
             Project: Drools
          Issue Type: Bug
          Components: executable model
    Affects Versions: 7.33.0.Final
            Reporter: Radovan Synek
            Assignee: Luca Molteni
         Attachments: stacktrace

CME is thrown from org.drools.modelcompiler.constraints.LambdaAccumulator.hashCode in OptaPlanner KIE Server extension tests. One of the failing tests is for example [1].

The executable model is switched on because the test creates SolverFactory from KieContainer [2], that is already compiler via a kie-maven-plugin - see the corresponding testing KJAR [3].
