Hi Alessio, On http://resteasy.jboss.org/ there is annoucement about 3.0.19.Final saying that after that new release will have deprecated some Resteasy 2 stuffs, like: * Resteasy 2 asynchronous invocation facility * Resteasy 2 client caching facility * Resteasy 2 client facility * Resteasy 2 interceptor facility * resteasy-hibernatevalidator-provider Are you still planning to do that? Asking because of there are tests using it ... just to know what to expect. Thanks, Katka
