Different coordinate system simply means different coordinate origins. 
This is the most natural behavior for the robot created for certain screen.
I didn't see a desktop within the OSes supported by JDK9 where multiple 
screens are treated as a separate displays rather then one extended desktop.
It seems JDK-8013116 should be reworked to correspond to the current 
state of multiscreen concept on the supported platforms.
