import java.io.IOException;
import java.net.HttpURLConnection;
import java.net.URL;

public final class HttpsTest {

	/**
	 * @param args
	 * @throws IOException
	 */
	public static void main(String[] args) throws IOException {
		HttpURLConnection httpsConn = null;
		URL url = new URL("https://www.google.com/");

		httpsConn = (HttpURLConnection) url.openConnection();
		System.out.println(httpsConn.getHeaderFields());
	}

}

This class gives this output on FreeBSD 6.0-RC1 and 5.4-STABLE with java  
1.5:
$ java HttpsTest
{}

on 6.0-RC1 with java 1.4:
$ java HttpsTest
{Content-Length=[151], null=[HTTP/1.1 302 Found], Date=[Wed, 12 Oct 2005  
19:52:46 GMT], Content-Type=[text/html], Server=[GFE/1.3],  
Location=[http://www.google.com]}

on Linux 2.6 with java 1.5:
$ java HttpsTest
{Content-Length=[151], Date=[Wed, 12 Oct 2005 19:50:24 GMT],  
Content-Type=[text/html], Server=[GFE/1.3],  
Location=[http://www.google.com], null=[HTTP/1.1 302 Found]}

Do other people have this?
