IllegalArgumentException while creating a new JPA knowledge session ------------------------------------------------------------------- Key: DROOLS-34 URL: https://issues.jboss.org/browse/DROOLS-34 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 6.0.0.Alpha1 Reporter: Ivo Bek Assignee: Mario Fusco Here (https://github.com/droolsjbpm/drools/blob/master/drools-persistence-jpa/s...) is incompatible constructor with KnowledgeBase instead of KieBase which causes the exception. Other methods that are using the constructor should be fixed as well. FYI I create the session this way: ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env); // where kbase is instance of injected KieBase
