Date Thu, 12 Oct 2006 10:30:35 GMT
[classlib][net]java.net.InetAddress.isReachable(NetworkInterface, int, int)   throws  NPE
-----------------------------------------------------------------------------------------

                 Key: HARMONY-1842
                 URL: http://issues.apache.org/jira/browse/HARMONY-1842
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Nikolay Bannikov


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

Test for reproducing:

import junit.framework.TestCase;
import java.net.NetworkInterface;
import java.net.InetAddress;
import java.util.Enumeration;

public class Test extends TestCase {       
        public void testInetAddress_isReachable_NetworkInterface_int_int() throws Exception
{ 

        InetAddress ia = InetAddress.getByName("localhost");
        Enumeration nif = NetworkInterface.getNetworkInterfaces();
        Object e = null;
        NetworkInterface netif = null;
        for (; nif.hasMoreElements(); ) {
	e = nif.nextElement();
	if (e != null) {
       	      netif = (NetworkInterface)e;
	}
           	ia.isReachable(netif, 10, 1000);
        }
    }
}
