IllegalAccessError when using MassData

[Dougems]

Pretty new here. Followed one of the YT vids. Got a basic app running. Can run mvn javafx:jlink to produce stand-alone app.

In order to do that I had to add a module-info.java file like this:

open module com.doug.main {
    requires com.almasb.fxgl.all;
}

Now I'm tinkering around with MassData. If I try to launch the app I get this when launching from within IntelliJ or from the command-line with mvn javafx:run:

If I get rid of module-info.java it runs fine. I'm kind of clueless about how to resolve this. Do I need to add something to module-info.java?

Hi, you are doing everything correctly. This appears to be a bug in that MassData is not exposed to the outside world. I'll open an issue so it gets tracked.
