Description
If using WebSockets, it always throws the NPE below:

This bug is always reproducible in my configuration.
It doesn't occur if comet/long-polling is used instead of websockets. Which means setting below will not trigger the bug:
<init-param>
<param-name>org.atmosphere.useWebSocket</param-name>
<param-value>false</param-value>
</init-param>
