UnifiedInvokerHAProxy replicants are not updated when other nodes undeploy beans
--------------------------------------------------------------------------------

                 Key: JBAS-5536
                 URL: http://jira.jboss.com/jira/browse/JBAS-5536
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Clustering, Remoting
    Affects Versions: JBossAS-5.0.0.Beta4, JBossAS-4.2.2.GA
            Reporter: Galder Zamarreno
         Assigned To: Galder Zamarreno
            Priority: Critical


We have a big regression at out hands. When we moved to unified 
invokers, we lost the ability for home/bean proxies to be updated 
when another node undeploys a bean. Why? 

ProxyFactoryHA.replicantsChanged looks something like this 
(the trace logs were added by me during debugging):

   public synchronized void replicantsChanged (String key, 
                                               List newReplicants, 
                                               int newReplicantsViewId)
   {
      try
      {
         if (homeInvoker instanceof InvokerProxyHA)
         {
            if (log.isTraceEnabled())
            {
               log.trace("Updating home proxy with new replicants " + target.getReplicants() + ", view=" + target.getCurrentViewId ());
            }
            ((InvokerProxyHA)homeInvoker).updateClusterInfo (target.getReplicants(), target.getCurrentViewId ());
         }
         if (beanInvoker instanceof InvokerProxyHA)
         {
            if (log.isTraceEnabled())
            {
               log.trace("Updating bean proxy with new replicants " + target.getReplicants() + ", view=" + target.getCurrentViewId ());
            }
            ((InvokerProxyHA)beanInvoker).updateClusterInfo (target.getReplicants(), target.getCurrentViewId ());
         }

         log.debug ("Rebinding in JNDI... " + key);
         rebindHomeProxy ();
      }
      catch (Exception none)
      {
         log.debug (none);
      }
   }

UnifiedInvokerHAProxy *does not* implement InvokerProxyHA, so unified invoker ha 
proxies will never have their replicants updated.
