java.net.Inet6Address.hashCode() always returns 0

Probably, the problem is due to copy-paste sources of
Inet6Address.java from InetAddress.java:

Inet6Address.java:
    ...
    public int hashCode() {
return address;
    }
 
but 'address' variable is not used in Inet6Address and always 0.

Please see an example demonstrating the bug below:
----------- IN6.java ----------------
import java.net.*;
import java.io.*;


public class IN6 {

    public static void main (String args[]){
       

        try {
            Inet6Address address = (Inet6Address)InetAddress.getByName(args[0]);
            System.out.println(address.toString());
            System.out.println("hashCode: " + address.hashCode());
        } catch (Exception e) {
            System.out.println(" " + e);
        }
    }
}
