My apologies for the bump. This seems to be the most apt place to put this information.
Since we're upgrading our server from JBoss EAP 6.4.x to EAP 7.1.x we ran into an issue with the default XSRF protection of GWT.
Undertow changes Session ID on authentication. To prevent Session Fixation.
Our fix has been to generate a long random string, stick it into the HttpSession and check that the client sends that blob on each request. We just overrode the XsrfProtectedService validation and the XsrfTokenService generation methods.
Even without Undertow this is possible with Servlet API 3.1 servers due to the addition of HttpServletRequest#changeSessionId() method.
With kind regards,

We are currently using it in production. The code hasn't changed since at least 2.6.0 (and probably earlier).The only problems we currently have are that sometimes the client doesn't fetch a new token on start or that the client has to refresh the browser after the session expired.
