Hello,

I add this 4 lines in my code before the session.dispose() and the problem
disapear :

        session.removeEventListener((WorkingMemoryEventListener)logger);
        session.removeEventListener ((AgendaEventListener)logger);
        session.removeEventListener((RuleFlowEventListener)logger);
        session.removeEventListener((RuleBaseEventListener)logger);

regards,

V.
