JsonHttpRemoteConfig.java

  //Change private to protected
  protected UrlMapper getUrlMapper(String method) {
    if ("DELETE".equals(method)) {
      return deleteMapper;
    } else if ("GET".equals(method)) {
      return getMapper;
    } else if ("POST".equals(method)) {
      return postMapper;
    } else {
      throw new IllegalArgumentException("Unknown method: " + method);
    }
  }

Reason for changing the getUrlMapper to protected is to allow me to write a plugin that will add custom end points to the selenium grid, which would allow me to stabilize my build on IE
