add the indicated line and it should work
(but you may get other problems, look you don't want, color etc)

public static void main(String[] args){
  SwingUtilities.invokeLater(new Runnable(){
    public void run(){
      JDialog.setDefaultLookAndFeelDecorated(true);//<-----------
      new FileChooserSizeTest();
}});
}

yes it works! if I add JDialog.setDefaultLookAndFeelDecorated(true);

but that's the only way you know?
because yes it give me looks and feel problems my project :(

the only other way I've seen is to add a componenLlistener,
and in componentResized() check the dimension - if under the min, reset to min
but I've not seen anyone happy with this solution - the component can be
dragged to small size, then 'snaps back' to the minimum

I think one of the changes introduced in Java 6 is that setMinimumSize() on a Window will actually enforce the set size, meaning that the window size will "freeze" if the user tries to make it smaller. I haven't tried this myself though, so I won't vouch for it.

...and I see now that the OP mentions he is already using Java 6, so never mind.

Try creating the file chooser like this

                JFileChooser fc = new JFileChooser(){
                    protected JDialog createDialog(Component parent) throws HeadlessException {
                        JDialog dialog = super.createDialog(parent);
                        dialog.setMinimumSize(new Dimension(200,200));
                        return dialog;
                    }
                };
