Hi Sergey,
I made the recommended changes (upgrade Atmosphere and disable the async
feature of CXFServlet), I got this error when trying to connect.
Seems there is a mismatch between the used CXF version (3.1.7) and Atmosphere
(2.4.3).
Best regards,
Anthony

Subject: Re: CXF 3.1 + Tomcat 8 + JAR-RS + Atmosphere + WebSocket
Hi Anthony
It all looks OK, except that you select the older Atmosphere version, it
has to be 2.4.3 - so start from removing that pom section where you get
an older version from the non-Central maven location.
The other thing - enabling async (suspended) continuations is not needed
for WebSocket (AFAIK), I'm not sure if it interferes, try disabling this
CXFServlet setting if using the latest Atmosphere does not help (it
would an issue of its own - but for now lets try to isolate where the
problem is)
