> 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].
