You're right: The invocation mode is `interface', not `virtual'.
I should have stopped with my first example, and left well enough
alone.
To the wider issue, though: It seems you are unhappy because you
and Java have different notions of what "virtual" means. You wrote
earlier,
>>> virtual method = method that can be overridden
>>> final method = method that can not be overridden
... and while this might be a perfectly good definition, it is not
Java's definition. The choice, then, is up to you: Stick with your
definition and remain miserable, or reconcile yourself with Java's
and become joyous and carefree. :)
