InetAddress.getByName behaves differently on Windows

InetAddress.getByName("0") returns "0/0.0.0.0" as expected on Solaris and Linux. However on Windows, a java.net.UnknownHostException is thrown. I've tried Win2000 Pro, Win2003 SE, and WinXP Pro. All with the same result.

Here's the test
---------------
import java.net.InetAddress;

public class test1 {
    public static void main(String argv[]){

        try {
           System.out.println( InetAddress.getByName("0") );
        } catch(java.net.UnknownHostException e) {
           e.printStackTrace();
        }

        return;
  
    }
}

Output from Windows
