Failing Test : api/java_net/InetSocketAddress/index.html#Ctor [InetSocketAddress0008]

The test tries to resolve different hosts using two differerent ways and compares results.
The problem is that this two ways both use InetAddress.getByName(host) method which
behaves differently in the case of iterative calls.

Here is a sample app that demonstrate the problem. The test class just
calls InetAddress.getByName(host).getHostName() twice and compare results.

===== test.java =====
import java.io.*;
import java.net.*;

public class test {
public static void main( String[] args ) throws Exception {
    PrintStream ref = System.out;
    PrintStream log = System.out;
     boolean passed = true;
    String host = "127.0.0.1";
    ref.println("Testing InetAddress.getByName(host).getHostName with: host="+host);
    for (int i = 0; i < 1000; i++ ) {
        /*
        The original JCK test calls "new InetSocketAddress", then InetSocketAddress.getAddress,
        and it's own function resolveHost(String) that calls InetAddress.getByName(String), and compares results.
        Since InetSocketAddress' ctor (String, int) just calls InetAddress.getByName(String), I've replaced such
        code with double call to InetAddress.getByName(host).
        // JCK test's source
        InetSocketAddress addr = new InetSocketAddress(host, port);
        InetAddress resolved = resolveHost(host);
        InetAddress returnedAddress = addr.getAddress();
        String returnedHost = addr.getHostName();
        String expectedHost = host;
        int returnedPort = addr.getPort();
        // end of JCK test's source
        */
        String returnedHost = InetAddress.getByName(host).getHostName();
        String expectedHost = InetAddress.getByName(host).getHostName();
        boolean check = true;
        if( !expectedHost.equals(returnedHost) ) {
            passed = false;
            check = false;
        }
        if( (!check || i==0) ) {
            ref.println( i==0 && check ? "Normal values are: " : "Test FAILED at step#"+i+" :");
            ref.println("getHostName() returns: " + returnedHost);
            ref.println(" expected: " + expectedHost);
            ref.println("----------------------------------------------");
        }
    }
    ref.println(passed?"passed":"failed");
};
};

How to reproduce:
=================
Run the following script on Windows 98 machine. (You may need to change JCK and JDK variables).
The script below creates necessary .JTE and .JTP files and then run the test using JavaTest in the
batch mode. After running test in the batch mode, the script will run the test without harness.

The first step (running the test in batch mode) is necessary to show the failure
since the bug is reproducible only when running with JavaTest harness (at least on the test Win98 machine)
and is not reproducible using the only JCK test that is demonstrated with the second step.
