Взял пример работы worker. Создал проект в FD, но после запуска ответа от воркера не приходит.

Output такой:
[Starting debug session with FDB]
[Main] HELLO
[Main] HELLO
[Main] HELLO
А должен быть, как я понимаю, такой:
[Starting debug session with FDB]
[Main] HELLO
[Worker] WORLD
[Main] HELLO
[Worker] WORLD
[Main] HELLO
[Worker] WORLD


Вот код примера:

protected var mainToWorker:MessageChannel;
		protected var workerToMain:MessageChannel;
		protected var worker:Worker;
 
		public function Main2():void 
		{
			/** 
			 * Start Main thread
			 **/
			if(Worker.current.isPrimordial){		
				worker = WorkerDomain.current.createWorker(this.loaderInfo.bytes);
 
				mainToWorker = Worker.current.createMessageChannel(worker);
				workerToMain = worker.createMessageChannel(Worker.current);
 
				worker.setSharedProperty("mainToWorker", mainToWorker);
				worker.setSharedProperty("workerToMain", workerToMain);
 
				workerToMain.addEventListener(Event.CHANNEL_MESSAGE, onWorkerToMain);
 
				worker.start();
 
				//Set an interval that will ask the worker thread to do some math
				setInterval(function():void{
					mainToWorker.send("HELLO");
					trace("[Main] HELLO");
				}, 1000);
 
			} 
			/** 
			 * Start Worker thread 
			 **/
			else 
			{			
				//Inside of our worker, we can use static methods to 
				//access the shared messgaeChannel's
				mainToWorker = Worker.current.getSharedProperty("mainToWorker");
				workerToMain = Worker.current.getSharedProperty("workerToMain");
 
				//Listen for messages from Main
				mainToWorker.addEventListener(Event.CHANNEL_MESSAGE, onMainToWorker);
			}
		}
		//Receive messages FROM the Main Thread
		protected function onMainToWorker(event:Event):void {
			var msg:* = mainToWorker.receive();
			//When the main thread sends us HELLO, we'll send it back WORLD
			if(msg == "HELLO"){
				workerToMain.send("WORLD");
			}
		}
		//Set an interval that will ask the worker thread to do some math
 
 
 
		//Receive messages FROM the Worker
		protected function onWorkerToMain(event:Event):void {
			//Trace out whatever message the worker has sent us.
			trace("[Worker] " + workerToMain.receive());
		}

Не могу понять в чем проблема?
