Ah, I see. You are calling ButtonData#setIcon(String) with that value. That
method obtains the location of the image as relative to the classpath, so the
leading "/" is required. I would probably use the setIcon(Image) version, and
define a default Image instance by calling Image.load(). But either way will
work.
