JOptionPane not displaying correctly?

Today I updated my jdk and docs from 7 to 8. I made a few changes to my program, and now when I try to have the program use JOptionPane, JLabel, ..., everything messes up. I made a separate tester class whose sole purpose is to run a single JOptionPane box and the error still occurred. Below is a picture of what the dialog box looks like. Is there something seriously wrong with Java 8?

import javax.swing.JOptionPane;



public class CirclePointTester
 {
    public static void main(String [] args)
    {
        String input = JOptionPane.showInputDialog("Enter the x coordinate of the circle");
            int xc = Integer.parseInt(input);
        String input2 = JOptionPane.showInputDialog("Enter the y coordinate of the circle");
            int yc = Integer.parseInt(input2);
        String input3 = JOptionPane.showInputDialog("Enter the height value of the circle");
            int height = Integer.parseInt(input3);
        String input4 = JOptionPane.showInputDialog("Enter the width value of the circle");
            int width = Integer.parseInt(input4);
    }
 }

Solution

  • For reference, here's a complete example that shows no regression on Mac OS X 10.9, Java 8. It may help you pin down the apparent regression.

    Addendum: In helpful comments, @mKorbel cites a number of similar problems with Java 8 on Windows with certain NVIDIA cards.
