Android's HttpURLConnection throws EOFException on HEAD requests

This small code snippet runs fine on my Mac's JVM. Unfortunately it crashes when executed on Android 4.2.

import java.net.HttpURLConnection;
import java.net.URL;

public class App
{
    public static void main( String... arguments ) throws Exception
    {
        HttpURLConnection connection = (HttpURLConnection) new URL( "https://github.com" ).openConnection();
        connection.setRequestMethod( "HEAD" );

        System.out.println( connection.getResponseCode() + "" );
    }
}

If I replace https://github.com with https://www.facebook.com it works fine but I'm failing to figure out why.

The exception does not contain a message; so here's at least the stack trace.

Turned out this is a known bug in Android's class implementation. Calling Connection.setRequestProperty( "Accept-Encoding", "" ); before connecting can be used as workaround.
