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 Priority: Critical 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].
