The fix for bug 4959456 was not complete. If the L&F is changed to GTK after creating a JFileChooser, then the first item in the folder is "null/".

This is reproducible in 1.5 beta1 and the latest build (b50).

Test case:


import javax.swing.*;

public class bug5045464 {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                JFileChooser fc = new JFileChooser();
                try {
                    UIManager.setLookAndFeel("com.sun.java.swing.plaf.gtk.GTKLookAndFeel");
                    SwingUtilities.updateComponentTreeUI(fc);
                    fc.showOpenDialog(null);
                    System.exit(0);
                } catch (Exception ex) {
                    System.err.println(ex);
                    System.exit(1);
                }
            }
        });
    }
}
