Swing GUI objects should be constructed and manipulated only on the event dispatch thread, after you've invoked UIManager.setLookAndFeel().

try {

} catch (UnsupportedLookAndFeelException e) {
    e.printStackTrace();
} catch (ParseException e) {
    e.printStackTrace();
}
EventQueue.invokeLater(new Runnable() {
    public void run() {
        JFrame frame = new JFrame();
        …
        frame.pack(true);
        frame.setVisible(true);
    }
});
