> With asynchronous mode of servlets a long running process never times out.
> In my tests I have a async servlet which calls starts a long running process. That process take longer then the configured timeout. But here never a timeout comes. The long running process can complete.
> According to the spec, the servlet should run into a timeout and the AsyncListener#onTimeout method is called for registered listeners.
> But this never happens in Wildfly 8.
> Here is a test servlet
> {code:title=AsyncServlet.java|borderStyle=solid}
> @WebServlet(urlPatterns = {"/AsyncServlet"}, asyncSupported = true)
> public class AsyncServlet extends HttpServlet {
>     private static final long serialVersionUID = 1L;
>     public AsyncServlet() {
>         super();
>     }
>     @Override
>     protected void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
>         res.setContentType("text/html");
>         final AsyncContext ac;
>         if (req.isAsyncStarted()) {
>             ac = req.getAsyncContext();
>         } else {
>             ac = req.startAsync();
>         }
>         ac.setTimeout(5000);
>         ac.addListener(new AsyncListener() {
>             @Override
>             public void onTimeout(AsyncEvent event) throws IOException {
>                 System.out.println("onTimeout");
>             }
>             @Override
>             public void onStartAsync(AsyncEvent event) throws IOException {
>                 System.out.println("onStartAsync");
>             }
>             @Override
>             public void onError(AsyncEvent event) throws IOException {
>                 System.out.println("onError");
>             }
>             @Override
>             public void onComplete(AsyncEvent event) throws IOException {
>                 // end of async processing -> end of response time
>                 System.out.println("onComplete");
>             }
>         });
>         // this processor takes longer then the timeout. e.g. 20 sec
>         ac.start(new Runnable() {
> 			@Override
> 			public void run() {
> 				try {
> 					Thread.sleep(20*1000); // working...
