fails with scaled resolution on primary device (960x540 by QuartzDebug) but pass with regular non-retina displays. At the moment of failure, popup coordinates for tooltip are clearly on the wrong display (negative x while mouse is far in positive area).
OS X 10.8.4 macmini4,1
jdk 7u40b31 and 8b96
primary retina 960x540 display is right, positive coordinates
secondary regular display to the left, negative x
