RFR: Request to sync April 2023 CPU changes into jfx:master+ backports to jfx20u, jfx17u, jfx11u

[Kevin Rushforth]

Hi Johan,

I request approval to sync changes from to the just-released April 2023 
CPU release into the 'master' branch of the 'jfx' repo. Here is the 
aggregate set of changes for the fixes:

https://github.com/kevinrushforth/jfx/compare/f28896aa63...cpu-2304-sync

NOTE: Since this is an integration of already-reviewed fixes, I will 
push it directly to the master branch of the jfx repo rather than via a 
pull request.

I also plan to push the backports of these changes to jfx20u (for 
20.0.1), jfx17u (for 17.0.7) and to jfx11u (for 11.0.19) .

NOTE: As with the mainline, since each is an integration of 
already-reviewed fixes, I will push directly to the master branch of the 
jfx20u, jfx17u, and jfx11u repos rather than via a pull request. For 
jfx20u repo, I will also push the 20.0.1* tags.

Thanks.
