Aha, yes, you are right. With the \n in the setText() string it fails as you
reported. Reopened. Thanks for following up on this.

import javax.swing.*;
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");
                textarea.setText("text0\n");
                textarea.setText("");
                this.setContentPane(textarea);
                this.pack();
        }
}
