Can you please check why a similar example using JFrame and button works fine, but the JFileChooser does not work?

        JFrame frame = new JFrame();
        JButton button = new JButton("1234567890");
        frame.add(button);
        frame.setVisible(true);
        frame.setEnabled(false);
        boolean enabled = button.isEnabled();
        System.out.println("enabled = " + enabled);
