URL constructor URL(URL context, String spec) is giving wrong output when spec is "" on solaris 8 with merlin build42.

How to reproduce the bug:

Test with the following code on Solaris 8 with Merlin build 42.

import java.io.*;
import java.net.*;

public class TestParseURL {

        public static void main(String[] arg) {

                try {
                  
                        String urlString = "http://a/b/c/d;p?q";
                        String urlspec = "";

                        System.out.println("url string" + urlString);
                        System.out.println("url spec " + urlspec);

                        URL context = new URL(urlString);

                        System.out.println("context " + context);
                        URL url = new URL(context , urlspec);

                        System.out.println("url string " + url.toString());
                } catch(Exception exp) {

                        System.out.println(exp.getMessage());
                }
        }
 
 } // End of class

Output of the above code for Merlin build 42 :
url stringhttp://a/b/c/d;p?q
url spec
context http://a/b/c/d;p?q
url string http://a/b/c/d;p


Output with JDK1.3 :
url stringhttp://a/b/c/d;p?q
url spec
context http://a/b/c/d;p?q
url string http://a/b/c/d;p?q


NOTE: When executed with merlin build 42 in the final url '?q' part is missing when spec is "".
