Using java3D 1.7.1 and JogAmp 2.4.0-rc-20210111, our program works great in both Windows and Linux,
except the following messages come out in all platforms:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.jogamp.java3d.JoglPipeline$1 (file: /home/test/lib/j3dcore.jar) to method sun.awt.X11GraphicsDevice.getScreen()
WARNING: Please consider reporting this to the maintainers of org.jogamp.java3d.JoglPipeline$1
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

Using the option --illegal-access=debug, we get the following stacktrace:

Thank you very much.
