Logging after making 1 request for a static page in a distributable webapp when the node was the only cluster member:

Problem is this in DataGravitatorInterceptor:

List resps = cache.callRemoteMethods(mbrs, dGrav, GroupRequest.GET_ALL, true, buddyManager.getBuddyCommunicationTimeout());
if (resps == null)
{
   log.error("No replies to call " + dGrav + ".  Perhaps we're alone in the cluster?");
   return new Object[]{null, null};
}

TreeCache.callRemoteMethods *will* return null if "we're alone in the cluster".
