java.net.InetSocketAddress.toString() throws NPE with unresolved address.

This is the test demonstrating the bug:
------------------------------------------------------------------
import java.net.*;
import java.io.*;


public class Test {

    public static void main (String args[]){
       
        System.out.println(new InetSocketAddress("unresolved", 12345));

    }
}
---------------------------------------------------------------------
output from the test:

#> java Test
Exception in thread "main" java.lang.NullPointerException
        at java.net.InetSocketAddress.toString(InetSocketAddress.java:159)
        at java.lang.String.valueOf(String.java:2039)
        at java.io.PrintStream.print(PrintStream.java:465)
        at java.io.PrintStream.println(PrintStream.java:602)
        at Test.main(Test.java:9)


Javadoc also does not specify the result in case of unresolved host.
It states for this method:

    Constructs a string representation of this InetSocketAddress.
    This String is constructed by calling toString() on the InetAddress
    and concatenating the port number (with a colon).
