note: "FXML JavaFX MavenArchetype" wizard does still work

tested on JDK 26.0.1 and 21.0.11 with NB 30 and master

edit: linux, x11, cinnamon

[neilcsmith-net]

Well, that's better than I get! Tried multiple times using NB30 with Temurin 26.0.1 and keep getting a segfault -

Short test: this is reproducible. If noone beats me to it I'll see if one of the OpenJFX versions compatible with JDK 21 work, if not, well then depending on FX will mean also requiring a newer JDK.
