You need to give more information?
How do you use it?
In what line of code do you get the error message?
Can't you post your project as a zip file, so we can see what exactly you have done and how?

I've always ignored these errors.
The first time I came across this error was whilst using TableView whilst setting the table CSS. As the CSS worked perfect and so does the app, I just ignored the error.

I believe that this error has something to do with using reflection with Java 9+, I read about it on the internet somewhere, I think it was most probably on Github...

Ignore this warning. It will happen with Java 9 / 10. It is harmless. It will not happen with Java 11+.
