@prrace I was thinking of a case which would actually throw HeadlessException
when run with `Djava.awt.headless=true` such as creating a frame or robot but
the exception msg can be null or default message from GraphicsEnvironment so
making it difficult to validate on different platforms. The current test works
well to validate both empty and null message.
