Integrating Spring MVC Spring Security with Undertow Web Container

Undertow's scalability reports in some tests have very little information on how to migrate a Spring MVC + Spring Security project to this new container from Tomcat.

Can anyone provide some kind of pointer on how to proceed with it?

Emphasize the claims to implement the Servlet 3.1 spec and is a container for the same.

I've built Spring into Jetty before, is this the same process or seems like it's not possible yet?
