Finalizers are inherently problematic and their use can lead to 
performance issues,
deadlocks, hangs, and other problematic behavior.

The problems have been accumulating for many years and the first step to
deprecate Object.finalize and the overrides in the JDK to communicate the
issues, recommend alternatives, and motivate changes where finalization 
is currently used.

The behavior of finalization nor any uses of finalize are not modified 
by this change.
Most of the changes are to suppress compilation warnings within the JDK.

Please review and comment.



Thanks, Roger
