I didn't know it was Artem's suggestion. And I still think that the
current fix is riskier than just returning null.
However, I agree that an app is likely to die either way. So if everyone
else is OK with this fix, let it be. I think that
CGraphicsEnvironment.getDefaultScreenDevice() should be rewritten too in
that case, since it should never encounter an empty devices list
anymore, so the current logic in that method looks redundant.
