Atmosphere on Tomcat/7.0.39 not Working with Servlet 3.0 Async API correctly

[confile]

I figured out that Atmosphere 1.1.0 RC3 is not Working with Servlet 3.0 Async API correctly on Tomcat/7.0.39

I got this error:

2013-06-11 01:52:02,269 [http-bio-8080-exec-4] WARN  websocket.DefaultWebSocketProcessor  - Failed invoking AtmosphereFramework.doCometSupport()

I fixed it with the following in my web.xml:

    <init-param>
      <param-name>org.atmosphere.useNative</param-name>
      <param-value>true</param-value>
  </init-param>

Then it is working. What is wrong with the Servlet 3.0 Async API?

Please use the mailing list :-) All samples works as expected, so something is wrong in your config.
