[ 100 seeking help ! Questions about the program to simulate ] HTTPS requests on BAE

Local operating normally casts will appear after errors
the deployment project to BAE

  
                  String requestUrl = "https://api.weibo.com/2/statuses/update.json";
                  try {
                      URL url = new URL(requestUrl);
                      HttpsURLConnection httpUrlConn = (HttpsURLConnection) url.openConnection(); //这句报错
  

/ / error prompt
java.lang.ClassCastException: sun.net.www.protocol.http.HttpURLConnection cannot be cast to javax.net.ssl.HttpsURLConnection

After View BAE BAE documentation found using OpenJDK 6
I use a local sun jdk 6
at BAE on openConnection () returns an instance of sun.net.www.protocol.http.HttpURLConnection
local returns the instance javax.net.ssl.HttpsURLConnection

not sun.net.www.protocol.http.HttpURLConnection local class can not find the corresponding packet access under this package
This package is not openjdk will own it ?
How do I resolve this problem ?
