This is done because the Robot sometime ends up clicking on Taskbar or side bar on Linux and we have had some related issue. Moving to centre helps to avoid those issues. Also, you just need to call frame.getLocationOnScreen to get the location along with the frame.bounds to get correct location. But this all is optional/preferred and it is fine you would like to keep the frame in left top.
