Bug Description:

  <Bug-Id:4957669 has not been correctly fixed yet>

  Creating a socket with a Japanese name throws not UnknowHostException
  but IllegalArgumentException.

  Sorry for reporting late. I noticed this but I didn't find time to
  investigate which japanese name caused the problem.

Steps to Reproduce (be specific):

Just try to compile the following code and run it.
------------------------------------------------

import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;

class SocketTest {
    public static void main(String[] args) {
        try {
            Socket s = new Socket("\u6749\u672c \u671d\u9999", 8000);
        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
