GLG2D is an implementation of Graphics2D that uses JogAmp JOGL
https://github.com/brandonborkholder/glg2d
http://brandonborkholder.github.io/glg2d/
Since your example uses Graphics2D then this is a good way to accelerate
your application!

" In order to render your scene using OpenGL instead of Java2D, just wrap your JComponent inside a GLG2DCanvas.

JComponent renderPane = ...

JFrame frame = new JFrame("My Game");
frame.setContentPane(new GLG2DCanvas(renderPane));
...

And that's it! "
