[jboss-jira] [JBoss JIRA] (WFLY-4599) AsyncListener.onComplete() not called if AsyncContext.dispatch() is called

[Stuart Douglas (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-4599?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Stuart Douglas resolved WFLY-4599.
----------------------------------
    Resolution: Done


There are no plans at this stage to do another 8.x release. This fix was part of Undertow so you should be able to just update the Undertow jars in your 8.x installation.

> Consider this code:
> {code}
> protected void doGet(HttpServletRequest req, HttpServletResponse resp) 
> {     
>         final AsyncContext asyncContext = req.startAsync();
>         asyncContext.addListener(new AsyncListener()
>         {
>             @Override
>             public void onComplete(AsyncEvent event) throws IOException
>             {
>                 System.out.println("complete");
>             }
>             @Override
>             public void onTimeout(AsyncEvent event) throws IOException
>             {
>                 System.out.println("timeout");
>             }
>             @Override
>             public void onError(AsyncEvent event) throws IOException
>             {
>                 System.out.println("err");
>             }
>             @Override
>             public void onStartAsync(AsyncEvent event) throws IOException
>             {
>                 System.out.println("start");
>             }
>         });
>         new Thread(new Runnable()
>         {
>             @Override
>             public void run()
>             {
>                 try
>                 {
>                     Thread.sleep(2000);
>                     asyncContext.dispatch("/path2");
>                 } catch (InterruptedException e)
>                 {
>                     e.printStackTrace();
>                 }
>             }
>         }).start();
>     }
> {code}
> When used in Wildfly 8.2.0.final {{complete}} will never be printed since {{onComplete()}} is not called by Wildfly when {{asyncContext.dispatch()}} is used even after {{path2}} has finished executing.
> On all other versions of wildfly, and other app servers like tomcat and jetty, {{complete}} will be printed.
