> 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.
