Hello I have to implement Asynchronous HTTP Request Processing, from this example with resteasy "http://docs.jboss.org/resteasy/docs/1.1.GA/userguide/html/Asynchronous_HTTP_Request_Processing.html".

The client is a web application using a recursive function based on XMLHttpRequest with a GET request. The purpose is to make a web push system and receive data only when event occurs. My solution it seems to work except sometimes an error is triggered in jboss log, fortunately the error is not fatal and my system does not crash but the message is very bothering, below the error, any idea or tips how to integrate a web client with resteasy  Asynchronous HTTP Request Processing or any particular config ?

thanks Davide
