问题
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);
}
}

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.

Code:

public class Test {
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
String input = JOptionPane.showInputDialog(
"Enter the x coordinate of the circle");
int xc = Integer.parseInt(input);
System.out.println(xc);
}
});
}
}
