Create or Open an existing Netbeans Platform Application.
Run the application with Java Platform set to JDK 16.
The following exception occurs:
{code:java}

This is happening because access to JDK Internals has been disallowed from JDK 16 onwards.

It used to show a warning in earlier JDK versions.
There are few other places where the Netbeans Platform is hacking into JDK internals:
