Below is a small example that demonstrates how NPE is raising from
TitledBorder.paintBorder()

-------------------------------------------------
import java.awt.*;
import javax.swing.*;
import javax.swing.border.*;


public class BorderTest {

    public static void main(String[] argv) {
        String title = "Test";
        JButton component = new JButton("Test");
        TitledBorder border;
        JFrame f = new JFrame("Test Frame");
        f.setBounds(100, 100, 100, 100);
        f.setVisible(true);
        Graphics g = f.getGraphics();
        border = new TitledBorder( title);
        border.paintBorder(component, g, 0, 1, 2, 3);
        f.dispose();
    }
}
-------------------------------------------------
The following is throwing from the test:
