The code ultimately does everything correctly. Some JavaFX components
expose a getChildren() method which doesn't actually do anything because
your supposed to use getItems() or something like that and it causes odd
behavior but you're using the right methods...
but I digress, JDK 11 switched to GTK3 by default which has caused some
bugs. Try setting:
wherever you add run args in your Maven project(I use Ant and have no
experience with Maven). It will force GTK2. I tried to run your program
myself but there doesn't seem to be a way to add local dependencies like
you can with Ant in Netbeans 9, causing a build fail and Netbeans 9
can't find a main class.

If I may ask, why are you sidestepping constructors and using static
everywhere? It works all the same, just never seen anyone write code the
way you did.
