I see "Scroll direction: Natural" check in mouse in SystemPreference which is by default checked, 
which causes down-wheel scroll to "move up" and up-wheel scroll to "move down" and if unchecked, then it causes reverse.
But I could not find anyway to find in Java in Robot how to get scroll type of macos or for other platforms. 
If you are aware, let me know..
I guess we always test with default settings..
