      Description

      I'm trying to deploy my jetspeed-2 based portal to jetty-6.
      My portal deploys successfully and working fine, but a get ConcurrentModificationException when i pressing logout link.

      Here is a stack trace:

      I think this issue is a result of the recursive Session.invalidate() invocation by
      org.apache.jetspeed.container.session.PortalSessionMonitorImpl.invalidateSession()
      org.apache.jetspeed.container.session.PortalSessionsManagerImpl.portalSessionDestroyed(PortalSessionMonitor)
      org.mortbay.jetty.servlet.AbstractSessionManager.Session.unbindValue(String, Object)

      I mean that Session.invalidate() calls Session.unbindValue() which calls above-listed stack and PortalSessionMonitorImpl.invalidateSession() calls Session.invalidate() again.
