The follow on work to adding the Cleaner is to replace uses of
finalization with uses of the Cleaner.
For the 'easy' cases in the java.base module, it is useful to introduce
a private Cleaner for the
java.base module. It is proposed to be held weakly, to allow it to
terminate on a lightly loaded
Webrev for Review:
The 2nd step is using the Cleaner.
- Empty finalize methods should (I think) be removed; but since they
are part of the public spec
the process needs two full releases; so the proposal is to deprecate
(The JEP 277 necessary changes will be updated when JEP 277
semantics are finalized)
- In a few cases, the code in the finalizer is redundant and if removed
an optimization of the handling of the finalizer and future removal
of the finalize method.
Thanks for comments and suggestions, Roger
