Not possible to configure cache with spring

Spring 4
Resteasy 3.0.6
Tomcat 7

Are using the spring configuration with the contextloaderlistener.
Have tried to configure server cache, http://docs.jboss.org/resteasy/docs/3.0.6.Final/userguide/html_single/#server_cache, but it's not apparent to me how, but could be a documentation issue.

Cant seem to register ServerCacheFeature in any way.

Current workaround:
Have extended ServerCacheFeature and added @Named @Provider annotations.

@Named
@Provider
public class MyCacheProvider extends ServerCacheFeature {

This seems to work, but it's not picking up the infinispan configuration in this way (the param names are not available in configuration).

<context-param>
        <param-name>server.request.cache.infinispan.config.file</param-name>
        <param-value>infinispan.xml</param-value>
    </context-param>

    <context-param>
        <param-name>server.request.cache.infinispan.cache.name</param-name>
        <param-value>MyCache</param-value>
    </context-param>
