[jdk21u-dev] RFR: 8315701: [macos] Regression: KeyEvent has different keycode on different keyboard layouts

[Goetz Lindenmaier]

I would like to backport this to fix the issue in 21. 

I ran the test. I can not pass it, but I see similar errors in 17, 21 and head.



     17 21   head
(1) yes yes  yes
(2) no  no   no  (Ctrl+Shift+7) or (Ctrl+7)?  Shift+7 prints '.'
(3) yes yes  yes
(4) yes yes  yes
(5) no  no   no  Alt == Option
(b) no  yes  yes Alt == Option


So I think this works as well as in head.
