Thanks, Muneer. Build 167 seems to have fixed that javadoc NPE. I have
updated https://issues.apache.org/jira/browse/DERBY-6856.
Cheers,

Hi Rick,
I was following your conversation in the core-libs mailing list. I am
glad to know that you got some guidance on new Cleaner based finalization.
In the mean time, recently derby reported javadoc issue
https://bugs.openjdk.java.net/browse/JDK-8177692 is fixed from JDK9
build 165 onwards.
Can you please confirm the fix. I am not seeing any about this on your
JIRA id https://issues.apache.org/jira/browse/DERBY-6856
Regards,
Muneer

Thanks again, Muneer. My conversation with the open-jdk list is linked
from https://issues.apache.org/jira/browse/DERBY-6932. That issue will
track the non-trivial work required to re-factor Derby's finalizers
and migrate them to the Cleaner-based pattern. In the meantime, I have
suppressed the finalizer deprecation warnings so that Derby will
continue to compile cleanly under JDK 9.
Thanks,
-Rick

Thanks, Rory. When I compile 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
