[jfx18, jfx17u, jfx11u] RFR: Request to backport April 2022 CPU changes

[Kevin Rushforth]

Hi Johan,

I request approval to backport the changes from the just-released April 
2022 CPU to jfx:jfx18 (for 18.0.1), jfx17u (for 17.0.3) and to jfx11u 
(for 11.0.15) .

https://github.com/kevinrushforth/jfx17u/compare/4af7ee97f3...cpu-2204-sync
https://github.com/kevinrushforth/jfx11u/compare/1c3d966688...cpu-2204-sync
https://github.com/kevinrushforth/jfx/compare/7e2cefba7f...18-cpu-2204-sync

For each repo, this is a straight backport (patches initially applied 
cleanly, but then the same merge conflict had to be resolved in each 
code line as was done in the mainline) of the two FX fix that went into 
the April CPU.

NOTE: Since this is an integration of already-reviewed fixes, I will 
push it directly to the jfx18 branch of the jfx repo, and to the master 
branch of the jfx17u and jfx11u repos rather than via a pull request.

Thanks.
