FireAllRulesRuleBaseUpdateListener to use a WeakReference<StatefulSession> to prevent memory leaks
--------------------------------------------------------------------------------------------------

                 Key: JBRULES-2422
                 URL: https://jira.jboss.org/jira/browse/JBRULES-2422
             Project: Drools
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: drools-core
    Affects Versions: 5.0.1.FINAL
            Reporter: Juergen
            Assignee: Mark Proctor


I had similar issues with StatefulSession (instantiated via JSR94 api) not being released / GCed

Investigating the Issue I found JBESB-1796

My problem was also caused by the session still being connected to a GC root via session -> FireAllRulesRuleBaseUpdateListener -> rulebase -> root

Wouldn't it be more robust to use a WeakReference to the session in org.drools.base.FireAllRulesRuleBaseUpdateListener? or the listener itself?
