Unfortunately the JavaFX menu bar is just as broken as the one in Swing. In particular (I'm sure there's more),

1. it gets very confused about the focus when alt-tabbing between windows (as alt, on Windows, also toggles focus on the menubar),

2. there is no attempt to solve the problem of submenus disappearing when you attempt to move the pointer towards them, which is solved in Windows and Qt with a delay, and in Mac OS and GTK with ... the solution that is actually documented in the OpenJDK wiki but not implemented: https://wiki.openjdk.java.net/display/OpenJFX/Menu+User+Expe...

So JavaFX might be high-quality in some way I haven't noticed, but to me its immediately noticeable qualities were its general slowness and brokenness.
