----------------------------------------------------------

The bug is in the following line in ClusteredSingleSignOn#deregisterLocal:

            ClusteredSession<OutgoingDistributableSessionData> clusteredSession = (ClusteredSession<OutgoingDistributableSessionData>) session ;

It incorrectly assumes every session tied to the SSO is a ClusteredSession, which is not true for non-distributable applications.

    The bug is in the following line in ClusteredSingleSignOn#deregisterLocal:

            // Invalidate this session, but do not propagate to other nodes
            ClusteredSession<OutgoingDistributableSessionData> clusteredSession =
                    (ClusteredSession<OutgoingDistributableSessionData>) session ;
