a finalize() method, if it exists, will be called _before_ the object is
and will only be called once by the GC (built-in) algorithm. The only
way a finalize() method will
be called more than once is if you explicitly call the finalize() method
yourself from Java source.
And if you do, this has no bearing on the eventual invocation caused by
the normal GC built-in mechanism
which will also invoke finalize() exactly once [more].
