> Currently,  the java.net.InetAddress.toString() is as below:
>     <code>
>     public String toString() {
>         return getHostName() + "/" + getHostAddress();
>     }
>     </code>
>     But actually the toString() should behave differently with getHostName()!
>     the Java spec for toString():
>     <spec>
>         Converts this IP address to a String. The string returned is of the form: hostname
/ literal IP address. If the host name is unresolved, no reverse name service loopup is performed.
The hostname part will be represented by an empty string.
>     </spec>
>     and the spec for getHostName() says:
>     <spec>
>     If this InetAddress was created with a host name, this host name will be remembered
and returned; otherwise, a reverse name lookup will be performed and the result will be returned
based on the system configured name lookup service.
>     </spec>
>     Spec shows that toString() shouldn't perform reverse name lookup while getHostName()
should!
>     A simple test show this bug:
>     <code>
>     public class ToStringTest{
>     public static void main(String[] args) throws Exception{
>         InetAddress addr = InetAddress.getByName("localhost");
>         System.out.println(addr);
>         InetAddress addr2 = InetAddress.getByAddress(new byte[]{127, 0, 0, 1});
>         System.out.println(addr2);
>     }
>     }
>     </code>
>     on RI, it outputs:
>         localhost/127.0.0.1
>         /127.0.0.1
>     and on Harmony, it outputs:
>         localhost/127.0.0.1
>         localhost/127.0.0.1
