[jboss-jira] [JBoss JIRA] (DROOLS-4996) NotSerializableException is thrown at the serialization of KieBase

NotSerializableException is thrown at the serialization of KieBase ------------------------------------------------------------------- Key: DROOLS-4996 URL: https://issues.redhat.com/browse/DROOLS-4996 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 7.25.0.Final Reporter: Róbert István Assignee: Mario Fusco Priority: Minor NotSerializableException is thrown at the serialization of KieBase when the 'when' part of a rule contains a query call. InterceptorMap static subclass doesn't implement the Serializable interface. When I corrected the source of MVELCompilationUnit and rebuild the drools-core.jar, the issue disappeared.
