> org.jboss.remoting.ConnectionNotifier.connectionTerminated() throws NullPointerExceptions from the following code:
>          ConnectionListener[] list = (ConnectionListener[])listeners.toArray(new ConnectionListener[listeners.size()]);
>          for(int x = 0; x < list.length; x++)
>          {
>             list[x].handleConnectionException(ex, client);  // <<== NPE's thrown here
>          }
> It seems that listeners got smaller between the call to listeners.size() and the call to listeners.toArray(), which could result in list having one or more null elements.
