The specification says JFileChooser.setCurrentDirectory(file) sets current dir to
a file or to a user's home if file is null.
However, for Metal LAF it sets current dir to the _canonical_ path of the given file or to the
_canonical_ path of the user's home if file is null.

In particular this means that symbolic links on a Unix machine will be expanded
and the getCurrentDirectory method will return file object which is not equal to
the one passed to setCurrentDirectory.

Either this should be documented in the javadoc or implementation should be changed.

This problem causes the failure of the following simple test
if the user's home is a symlink to some other directory:

========== FileTest.java ===========
import java.io.*;
import javax.swing.*;

public class FileTest {

    public static void main(String[] s) {
        File f=new File(System.getProperty("user.home"));
        JFileChooser ch=new JFileChooser();
        System.out.println("User's home:" + f);
        System.out.println("Current dir:" +ch.getCurrentDirectory());
        if (f.equals(ch.getCurrentDirectory()))
            System.out.println("passed");
        else
            System.out.println("failed");
    }

}

Please note that this problem is specific to Metal LAF.
The same piece code works correctly with Motif LAF:
========= FileTest1.java =========
import java.io.*;
import javax.swing.*;

public class FileTest1 {

    public static void main(String[] s) throws Exception {
        UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); // ! CHANGE LAF
        File f=new File(System.getProperty("user.home"));
        JFileChooser ch=new JFileChooser();
        System.out.println("User's home:" + f);
        System.out.println("Current dir:" +ch.getCurrentDirectory());
        if (f.equals(ch.getCurrentDirectory()))
            System.out.println("passed");
        else
            System.out.println("failed");
    }

}
========= sample run =========
java -Duser.home=/net/mars/export2/gor FileTest1
User's home:/net/mars/export2/gor
Current dir:/net/mars/export2/gor
passed

java version "1.2.2"
Classic VM (build JDK-1.2.2-001, native threads, symcjit)

Make a JFileChooser in a GUI that opens in the current directory:

JFileChooser fc = new JFileChooser(".");
int retval = fc.showOpenDialog(this); //assume this is a JFrame
if (retval == JFileChooser.APPROVE_OPTION) {
File dir = fc.getCurrentDirectory();
System.out.println("Dir is: " + dir.getName());
}

If we are in d:\users\mary,and select a file in that directory,
this only prints out:
Dir is: mary
It should print :
Dir is: d:\users\mary
or
Dir is: \users\mary

How are you supposed to get the complete pathname of the file
otherwise?
