HTMLUnit不处理jsonp请求

I am trying to crawl my GWT app with HTMLUnit, but for a certain page the desired content is not returned. The GWT page contains a dynamically added javascript which makes a jsonp request to a gae server. I already debugged the server code, and the breakpoint is hit, but at this time the htmlunit code is already finished and the returned content is not complete.I am trying to crawl my GWT app with HTMLUnit,
