    Seam-Security Preventing Resteasy Async Calls

    mister_s Newbie

      Hi everyone,

       

      I'm building a REST web-application using JBoss 7.1, Resteasy and Seam-Security. While regular REST calls work splendid, when adding seam-security to the application, asynchronous calls throw an exception.

       

      Here's my example application:

       

      {code}

      package com.example.test.polling;

       

      import javax.ws.rs.ApplicationPath;

      import javax.ws.rs.core.Application;

       

      @ApplicationPath("/")

      public class JaxRsConfig extends Application {

      }

      {code}

       

      and the REST endpoint:

       

      {code}

      package com.example.test.polling;

       

      import javax.ws.rs.GET;

      import javax.ws.rs.Path;

      import javax.ws.rs.Produces;

      import javax.ws.rs.core.MediaType;

      import javax.ws.rs.core.Response;

      import javax.ws.rs.core.Response.ResponseBuilder;

       

      import org.jboss.resteasy.annotations.Suspend;

      import org.jboss.resteasy.spi.AsynchronousResponse;

       

      @Path("/poll")

      public class PollingRestService {

       

          @GET

          @Path("/get")

          @Produces(MediaType.TEXT_PLAIN)

          public String syncGet() {

              System.out.println("syncGet() was called");

              return "all ok";

          }

       

          @GET

          @Path("/async")

          @Produces(MediaType.TEXT_PLAIN)

          public void getAsync(@Suspend(1000) final AsynchronousResponse response) {

              Thread t = new Thread() {

                  @Override

                  public void run() {

                      try {

                          System.out.println("getAsync(): running thread");

                          sleep(10 * 1000); // 10s

       

                          ResponseBuilder ok = Response.ok("all ok on this side", MediaType.TEXT_PLAIN);

                          Response jaxrs = ok.build();

                          response.setResponse(jaxrs);

       

                          System.out.println("getAsync(): response sent");

                      } catch (Exception e) {

                          e.printStackTrace();

                      }

                  }

              };

              t.start();

          }

      }

      {code}

       

       

      This very code works beautifully as long as seam-security is not present. When adding seam-security to my pom file's dependencies (I don't even have to use it in some class!), calling the async method (using "/poll/async" in my browser) produces the following exception:

       

      {code}

      {code}

       

      It looks to me that the call somehow gets routed to SynchronousDispatcher, and then fails.

       

      Has anyone an idea why this happens, and how I can prevent it (and thus resolve the exception)? Why has adding seam an effect on how the call is dispatched? Is it a bug in seam (should I file an issue)?

       

      I'm using the latest versions of everything:

      • JBoss AS 7.1.0.Final
      • seam-security 3.1.0.Final
      • resteasy 2.3.1.GA
