I installed Java9 as described here. This works without any problems for any projects I tried without JavaFX. Unfortunately my company runs its UIs with JavaFX and those packages seem to be missing.
I also evaluated using the openjdk plus the openjfx package, but this does not exist for Java9 yet.
What would be the way to install Java9 with JavaFX?
java -version
gives java 9.0.4.java -version
since it's crucial to see which version of JDK you have installed (you posted a link to instructions for OpenJDK 8 and thejava
version is 9.x).
