[Reposting to correct list]

I think I have run into a regression when trying Servlet 3.0 async
support on top
of Grizzly.

Following is a very simple servlet:

  @WebServlet(urlPatterns = {"/test"}, asyncSupported = true)
  public class TestServlet extends HttpServlet {

      public void doGet(HttpServletRequest req, HttpServletResponse res)
              throws IOException, ServletException {

          if (!req.isAsyncSupported()) {
              throw new ServletException("Async not supported when it
should");
          }

          req.startAsync().complete();
      }
  }


When I access it, I get the attached stack trace.

To reproduce, deploy the attached WAR and access /async/test

Any help/hints appreciated.

Thanks!


Jan
