    Affects Versions: 5.3.0.Final
         Environment: Linux, Java 1.6.0_24

When loading a Drools Flow StatefulKnowledgeSession with JPAKnowledgeService.loadStatefulKnowledgeSession, AbstractEventSupport.listeners has 2 listeners added to it. When the StatefulKnowledgeSession is disposed() only 1 of the listeners is removed. In the attached test this causes 100 ReteooStatefulSession objects to stay alive.
