java - Cannot access HTTPS from Weblogic

Question

I have a problem with Weblogic accessing an HTTPS server, I can access other HTTPS urls, like google or microsoft. The code that tries to connect to the url is:

URL url = new URL("https://myserver.com");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setRequestProperty("User-Agent", "Mozilla/5.0");

// fails here
responseCode = connection.getResponseCode();

I get the following stack trace:

java.io.IOException: Connection closed, EOF detected

In Weblogic's console I have the following setting set to true: Environment > Servers > [my server] > SSL > Advanced > Use JSSE SSL

If I disable that property I get the following stack trace:

The server I try to access has a verified certificate and browsers don't complain about it.

Thanks

Eventually it worked by setting these in the Weblogic arguments:

-DUseSunHttpHandler=true 
-Dssl.SocketFactory.provider=sun.security.ssl.SSLSocketFactoryImpl 
-Dssl.ServerSocketFactory.provider=sun.security.ssl.SSLSocketFactoryImpl
