When I compile Apache Derby using JDK 9 build 167, I see several
instances of the following warning:
warning: [deprecation] finalize() in Object has been deprecated
The javadoc for java.lang.Object.finalize() suggests that affected
classes should migrate their finalization to a coding pattern based on
the newly introduced java.lang.ref.Cleaner class. I am hesitant to try
my hand at this without more guidance. Can you point me at a tutorial or
list of best practices for implementing Cleaner-based finalization?
Thanks,
-Rick
