D2DViewHandler, getResourceURL(FacesContext context, String path) checks to see if the path contains a leading '/'. If so, it blindly appends the request context path, whether or not the given path already contains the context root path. This conflicts with the behaviour of the ResourceRegistry, which returns URLs that contain the root context path, and makes it difficult to use a URL derived from the ResourceRegistry on any component that first calls getResourceURL(..) to transform a path. We should first check if the given path argument contains the context path before appending, if it does, we should simply return the path unchanged, as we do if the path does not contain a leading '/'.
