write once, run anywhere and never use native method calls to maintain 
independence.
It's always been possible for getClass() to return a non-public class and for the Method invoke in the code example to fail with IllegalAccessException. You may have just got lucky in the past.  At some point then I would expect the JavaFX modules to not be open by default so maybe now is the time to fix the issues. You can run with `--illegal-access=warn` to help track down other code that may be accidentally trying to access members of JDK internal classes.  You can run with `--illegal-access=deny` to see how that code behaves when the classes in the JDK modules are not open for illegal access.
