FYI. "the default value of the launcher option --illegal-access is now deny rather than permit"
See also https://www.oracle.com/java/technologies/javase/16-all-relnotes.html ➜ JEP 396: Strongly Encapsulate JDK Internals by Default Strongly encapsulate all internal elements of the JDK by default, except for critical internal APIs such as sun.misc.Unsafe. Allow end users to choose the relaxed strong encapsulation that has been the default since JDK 9. With this change, the default value of the launcher option --illegal-access is now deny rather than permit. As a consequence, existing code that uses most internal classes, methods, or fields of the JDK will fail to run. Such code can be made to run on JDK 16 by specifying --illegal-access=permit. That option will, however, be removed in a future release.
