JSONObject wraps a real JavaScriptObject, so using:
JavaScriptObject unwrapped = json.getJavaScriptObject();
JavaScriptObject result = process(unwrapped);
json = new JSONObject(result);
public native JavaScriptObject process(JavaScriptObject o) /*-{
return $wnd.myJavascriptFunction(o);
}-*/;
should do what you want.
$wnd.myJavascriptFunction will get and return a normal
javascript object.
