Hi Alan, Mandy,
I looked at a few of the many uses of finalize and the likely changes.
The zip Inflater and Deflater are relatively simple cases.
Some finalizers are not used and can be removed.
The sun.net.www.MeteredStream example subclasses PhantomCleanable to add
the state and cleanup
Some of the harder cases will take more time to disentangle the cleanup
For example, ZipFile, and FileIn/OutputStream (Peter has prototyped this).
