How to get the exact cursor position on Y-axis?

Question

The e.getYOnScreen() on MouseEvent not returning the exact position on the content pane! When I click at the (0,0) location in the JFrame, its returning (0,30).
It may be the height of the frame title. How can I access the height of the JFrame title?

I have already tried adding MouseListener to frame as well as content pane. But, there is no significant difference.I have trouble believing this. Here where I add the mouselistener to the content pane, it works perfectly:
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
class MousePositionTest2 extends JFrame
    private JTextField xPositionField = new JTextField(3);
    private JTextField yPositionField = new JTextField(3);
    public MousePositionTest2(String s)
        super(s);
        JPanel contentPane = (JPanel)getContentPane();
        contentPane.setPreferredSize(new Dimension(400, 400));
        contentPane.setLayout(new FlowLayout());
        contentPane.add(new JLabel("Click Location: "));
        contentPane.add(xPositionField);
        contentPane.add(yPositionField);
        xPositionField.setEditable(false);
        yPositionField.setEditable(false);
        contentPane.addMouseListener(new MyMouseListener());
    private class MyMouseListener extends MouseAdapter
        @Override
        public void mouseReleased(MouseEvent e)
            xPositionField.setText("" + e.getPoint().x);
            yPositionField.setText("" + e.getPoint().y);
            super.mouseReleased(e);
    private static void createAndShowUI()
        JFrame frame = new MousePositionTest2("MousePositionTest2");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    public static void main(String[] args)
        java.awt.EventQueue.invokeLater(new Runnable()
            public void run()
                createAndShowUI();
}
