How to use with proxy username and password ?

Hii,
I am working behind the proxy network.
I tried arguments like following but it is not working.

-Dhttp.proxyHost=myproxy Dhttp.proxyPort=3128
-Dhttps.proxyHost=myproxy -Dhttps.proxyPort=3128

Following allows me add host and port of proxy, but I required to username and password as well.
connectionPolicy.setProxy(new HttpHost(InetAddress.getByName("proxy.company.com"), 12345));

I also tried following for authentication

final String authUser = "user";
final String authPassword = "password";
Authenticator.setDefault(
   new Authenticator() {
      @Override
      public PasswordAuthentication getPasswordAuthentication() {
         return new PasswordAuthentication(
               authUser, authPassword.toCharArray());
      }
   }
);

System.setProperty("http.proxyUser", authUser);
System.setProperty("http.proxyPassword", authPassword);

How can I use username and password for authentication for proxy.

該 issue 提到了入口點 connectionPolicy.setProxy 和 Java Proxy 屬性，但沒有指出檔案或測試。首先追蹤 Java SDK 中如何套用 Proxy 設定，以及是否支援經過驗證的 Proxy 憑證。完成標準是確立受支援的使用者名稱/密碼設定，或透過一個經過驗證的範例記錄這項限制。
