public class textarea extends JFrame {
        public static void main(String[] a) {
                (new textarea()).show();
        }
        public textarea() {  
                JTextArea textarea = new JTextArea(10, 40);
                textarea.setText("text0\n");
                textarea.setText("");
                this.setContentPane(textarea);
                this.pack();
        }
}

Note that this is very similar to bug 13230.
