URLDecoder fails with certain input with merlin build 46 on Solaris. Its throwing java.lang.IllegalArgumentException with certain input. Same test passed with jdk1.3.

How to reproduce the problem:

1. Take the following code.

public class EncodeDecode {

        public static void main(String[] args) {

        String str = "aslf alsf alsdjf";
 
        if(args.length > 0)
                str=args[0];
    
 
        String encStr = URLEncoder.encode(str);
        System.out.println("Encode string " + encStr);

        String decStr = URLDecoder.decode(encStr);
        System.out.println("Decoded String " + decStr);


        }

}


2. Execute as shown below.

java EncodeDecode 'asdf @$'
	or
java EncodeDecode fdadf@$

On execution as shown above output will be like this:

% java EncodeDecode fds@$
Encode string fds%40%24
Exception in thread "main" java.lang.IllegalArgumentException: URLDecoder: Incomplete trailing escape (%) pattern
        at java.net.URLDecoder.decode(URLDecoder.java:150)
        at java.net.URLDecoder.decode(URLDecoder.java:72)
        at EncodeDecode.main(EncodeDecode.java:21)


Other Information:

1. Its passed with jdk1.3 on solaris 8.
