[ https://jira.jboss.org/browse/JBRULES-2794?page=com.atlassian.jira.plugin... ] Anatoly Polinsky updated JBRULES-2794: -------------------------------------- Labels: drools-core drools-flow (was: drools-core) Description: Effected: Drools Flow and Drools Core -------------------------------------------------------- Unfortunately it is not a consistent behaviour, but happens quite often. This is not observed at all when running with e.g. 50 threads. java.util.concurrent.ExecutionException: org.drools.RuntimeDroolsException: Unexpected exception executing action
