at http://docs.jboss.org/resteasy/docs/3.1.4.Final/userguide/html/Installation_Configuration.html#resteasy_modules_in_wildfly we list RESTEasy modules and we say which are loaded by default and which aren't. I'm thinking we should actually revisit that part of the documentation, given a module being loaded by default or not is really some depending on the container. We could possibly even have a given RESTEasy version with a different set of modules being loaded by default on different WildFly versions.
