Why does Java resize a Window to 1x1 pixel when HDMI is unplugged (and does not resize back when HDMI is plugged)

Thanks, I can restore the size with your suggestion: I'm now using a 
scheduled executor service to check size and if it is not full screen 
remove full screen and set full screen window again. However, the Window 
does not show - it is not rendered. I tried setVisible(true) again, but 
no effect.
