This behavior occurs with the latest mustang build, b79. It does not occur with b66. This occurs on Linux and Solaris platforms.

Clicking on swing components present in a blocked JFrame changes the cursor shown. I've a JFrame on which I have a JButton and JTextField. The frame is blocked by a modal dialog. When I move the mouse over the JTextField, default cursor is shown. When I click on the text field, the cursor changes to text cursor. Even when I move the mouse over the button, the cursor shown is the same. Now, if I click anywhere on the frame outside the text field, the cursor changes to default cursor.

This behavior is not reproducible with awt components.

To reproduce, run the code below:

import javax.swing.*;
import java.awt.FlowLayout;

public class TestCursor {
    public static void main(String[] args) {
        JFrame f = new JFrame("Frame");
        JDialog d = new JDialog(new JFrame(), "Dialog");
        d.setModal(true);
        d.setSize(100, 100);
        d.setLocation(200, 200);
        f.setSize(200, 200);
        f.getContentPane().setLayout(new FlowLayout());
        f.getContentPane().add(new JButton("Button"));
        f.getContentPane().add(new JTextField(15));
        f.getContentPane().add(new JTextArea(5, 10));
        f.setVisible(true);
        d.setVisible(true);
    }
}
