[kaffe] java.net.InetAddress.getAllByName returns wrong value for localhost

[Ito Kazumitsu]

Hi,

I am afraid there is something wrong around java.net.InetAddress.

First, I patched InetAddress.java for debugging:

bash-2.05b$ diff -u java/net/InetAddress.java.orig java/net/InetAddress.java

     for (int i = 0; i < iplist.length; i++)
       {
-        if (iplist[i].length != 4)
+        if (iplist[i].length != 4) {
+         System.err.println("i=" + i + " iplist[i].length=" + iplist[i].length);
+         for (int j = 0; j < iplist[i].length; j++) {
+           System.err.print("" + iplist[i][j] + ".");
+         }
+         System.err.println();
+         System.err.flush();
           throw new UnknownHostException (hostname);
+       }
 
         // Don't store the hostname in order to force resolution of the
         // canonical names of these ip's when the user asks for the hostname

Then I ran the following test.

bash-2.05b$ cat TestInetAddress.java
import java.net.InetAddress;
public class TestInetAddress {
    public static void main(String args[]) throws Exception {
        String host = args[0];
        InetAddress ia = InetAddress.getByName(host);
        System.out.println(host + " = " + ia);
    }
}
