Yes our code works fine with 1.8.5.3.
Controller code as requested:
/**

* Run the listener
*/
public void run()
{
// tell Grizzly to use our logger
LoggerUtils.setLogger(new GrizzlyLoggingBridge(log));
sel = new SelectorThread();
sel.setPort(port);
sel.setEnableNioLogging(true);
con = new Controller();
con.setReadThreadsCount(readThreadsCount);
sel.setController(con);
sel.setMaxThreads(maxThreads);
sel.setMinThreads(minThreads);
sel.setKeepAliveTimeoutInSeconds(keepAliveTimeoutInSeconds);
sel.setSsBackLog(backlog);
// pre-register the JMX beans
// try
// {
// sel.preRegister(mbs, new
ObjectName("Grizzly:type=GrizzlyKeepAliveStats,name=GrizzlyKeepAliveStats"));

ObjectName("Grizzly:type=GrizzlyRequestGroupInfo,name=GrizzlyRequestGroupInfo"));
// sel.preRegister(mbs, new
ObjectName("Grizzly:type=GrizzlyRequestInfo,name=GrizzlyRequestInfo"));
// }
// catch (Exception e1)
// {
// // not a fatal error but log it
// log.error("Failed to pre-register Grizzly JMX beans.");
// }
// create the JMX manager
// sel.setManagement(management);
//Get and set up the Grizzly filter
ICallbackAdapter adapter =
(ICallbackAdapter)SpringBeanFactory.getInstance().getBean(GRIZZLY_ADAPTER);
adapter.setCallbackKey(CALLBACK_KEY);
sel.setAdapter((Adapter)adapter);
//Get and set up the Grizzly adapter
final AsyncHandler handler = new DefaultAsyncHandler();
ICallbackFilter filter =
(ICallbackFilter)SpringBeanFactory.getInstance().getBean(GRIZZLY_FILTER);

sel.setEnableAsyncExecution(true);
if (log.isDebugEnabled() || log.isInfoEnabled() )
{
sel.setDisplayConfiguration(true);
}
else
{
sel.setDisplayConfiguration(false);
}
try
{
sel.initEndpoint();
// switch on JMX monitoring

log.debug("Switching on Grizzly JMX monitoring.");
}
