I don't quite understand what this change in RemoteServiceServlet has to do with UrlBuilder...
http://gwt-code-reviews.appspot.com/754803/diff/21001/22002 File user/src/com/google/gwt/user/server/rpc/RemoteServiceServlet.java (right): http://gwt-code-reviews.appspot.com/754803/diff/21001/22002#newcode79 user/src/com/google/gwt/user/server/rpc/RemoteServiceServlet.java:79: String contextRelativePath = URLDecoder.decode(modulePath.substring(contextPath.length())); Beware! URLDecoder will decode "+" into a space, whereas it might really mean a "+". What I mean is that this is probably a breaking change. http://gwt-code-reviews.appspot.com/754803/show -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
