> Harmony implementation of java.net.InetAddress.isReachable(NetworkInterface, int, int)
  throws NPE while RI  returns valid result.

> import java.util.Enumeration;

{ 
>         InetAddress ia = InetAddress.getByName("localhost");
>         Enumeration nif = NetworkInterface.getNetworkInterfaces();
>         Object e = null;
>         NetworkInterface netif = null;
>         for (; nif.hasMoreElements(); ) {
