Summary
-------
Remove the terminally deprecated method `sun.misc.Unsafe.defineClass`.
There is a public supported replacement since Java 9, `MethodHandles.Lookup.defineClass`, and there has been much outreach explaining this public method and encouraging developers responsible for key libraries and applications to use it.
