I don't suppose that this is possible, perhaps with reflection?

The idea is for a plugin to extend a class, but the class is not a
public class, so can only be extended from within the same package.

If the jar file was unsealed, then a class could be created within the
plugin that is in the same package, is public and extends the non-
public class.
