First line of the README:
&gt; Important: TornadoFX is not yet compatible with Java 9/10

well, it does work if I run it from IntelliJ :slightly_smiling_face:
So it is at least partially compatible. The problem I'm struggling with is obviously with gradle setup, not tornadofx

Interesting. I wonder if IntelliJ is running it on JDK 8 under the covers.

It does not, I had to jump through all the usual `module-info.java` hoops before I was able to run it. Also Java `*.class`es in the project have bytecode version 54.0 (Java 10).

The incompatibilities are mostly caused by private com.sun classes that were changed to public APIs;  most of tornadofx doesn’t use them however
