> I was able to reproduce the issue and change certainly solves the issue when i start the jtreg test from default display (Without external display launching test from retina/ With external display as default and launching jtreg test from external display). But when i run jtreg test from retina and keep external display as default, test still fails with same behaviour as seen without this fix.

The problem in the multiscreen environment was caused by using the wrong NScreen to calculate the "y" coordinate. The "NSScreen mainScreen" returns the "Returns the screen object containing the window with the keyboard focus" actually the window where the terminal is located, not the screeen(0,0) expected by the test.
