Java JOptionPane Text Unreadable

When I use this code

import javax.swing.*;
public class Swag {
public static void main ( String[] args) {
String name = JOptionPane.showInputDialog("What is your name?");
  String input = JOptionPane.showInputDialog("How old are you?");
int age = Integer.parseInt(input);
  System.out.print(" Hello, " +name);
System.out.println("Next year you'll be " +(age+1));
}
}

And run it, it ends up looking like thisH1765.png I'm running windows 8, the latest x64 JDK, no type of custom font or anything that I know of. I've run this through eclipse, CMD, and uninstalled and reinstalled Java. I tried using another example of JOptionPane usage from a site and running it, still looks the same.
