Swing rendering seems to be broken in Java 8

Here’s a simple Java program that I wrote to test Swing GUI in Java 8 (I use JDK 1.8.0_05-b13):

 

import javax.swing.JFrame;
import javax.swing.JButton;

public class HelloWorld extends JFrame {

public static void main(String[] args) {
JFrame myWindow = new HelloWorld();

// Creating and adding a button the the container
JButton myButton = new JButton (“Click me”);
myWindow.add(myButton);

myWindow.setSize(200,300);
myWindow.setTitle(“Hello World”);
myWindow.setVisible(true);
}
}

The program renders fine on MAC OS:
HelloWorld_java8_MAC

But this is what I get on Windows 7 Ultimate with JDK 1.8.0_05-b13:
HelloWorld_java8_Windows

In JDK 1.7 under Windows it works fine:

HelloWorld_java7_Windows

I’ve asked some people to try the same code with the same version of Java and they don’t see this issue. The only other reason I  can think of is that I’m connecting to the Windows VM remotely using Remote Desktop Connection from MAC OS. There’s is a chance that that program screws things up.

I’ve submitted a bug report to Oracle anyway, but if you use Java Swing, test your code before migrating to Java 8.
