In our projetcs we make heavy use of resteasy-vertx. After upgrading from Vert.x 3.9.4 to 4.0.0.Beta3 we cannot start our applications anymore, because the method io.vertx.core.http.HttpServerRequest#rawMethod was removed in Vert.x 4.x (see https://github.com/eclipse-vertx/vert.x/commit/d3ba036bf0b165c5b8a0aa1a29a9a6d78830fbbd) but this method is used in org.jboss.resteasy.plugins.server.vertx.VertxHttpRequest.
