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}

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
