This patch looks fine in general.

Does @inheritDoc inherit @deprecated?  What does the javadoc of javax.imageio.stream.* look like?

+      * @deprecated Finalization is deprecated and should not be used.
+      *             See {@link Object#finalize} for the explanation and recommended replacement.

Also, the second line is rather long and might be good to break into two lines?
