macOS 14.2.1
To reproduce:

- run the attached program (TextField inside a JFXPanel)
- switch input language to Arabic
- type 'a'

NPE gets thrown with Hebrew and Russian input.
Japanese, French, and German seem to work except for some key strokes such as semicolon (;) in German and tick (') in French.

(the same scenario works fine in with JTextField in a regular FX application).
