I think `EventQueue.invokeAndWait()` should be used instead of `SwingUtilities.invokeAndWait()` for AWT test.

Is it possible to render the checkbox into the buffered image directly and then do the testing?

This way, you can avoid creating the frame, adding component to it, using robot for screen capture.
