[jcifs] Has anybody else seen problems with file names that start with a dot?

Actually this appears to be just poor parsing on the part of the
java.net.URL class. Unfortunately I don't think we cannot write our own
parser and support java.net.URL at the same time because of the way the
protocol handlers work.

The below test program illustrates the problem:

$ cat HttpURL.java
import java.net.*;

public class HttpURL {

        public static void main( String[] args ) throws Exception {
                URL u = new URL( new URL( args[0] ), args[1] );
                System.out.println( u );
        }
}

$ java HttpURL "http://server/apath/" "filename.txt"
http://server/apath/filename.txt
$ java HttpURL "http://server/apath/" ".filename.txt"
http://server/apath/.filename.txt
$ java HttpURL "http://server/apath/" ".a#filename.txt"
http://server/apath/.a#filename.txt
$ java HttpURL "http://server/apath/" ".#filename.txt"
http://server/apath/#filename.txt           <-----OOPS
$ java HttpURL "http://server/apath/" "..#filename.txt"
http://server/#filename.txt                 <----WORSE
$ java HttpURL "http://server/apath/" "...#filename.txt"
http://server/apath/...#filename.txt

Currently I don't think I can take this problem further and can only
recommend that you avoid this particular class of filenames.

Hopefully the java.net.URI class is better...

A program should be written to  model the concepts of the task it
performs rather than the physical world or a process because this
maximizes the  potential for it  to be applied  to tasks that are
conceptually similar and, more  important, to tasks that have not
yet been conceived.
