> Please review this enhancement to add a new JFR event, generated whenever a finalizer is run.
> (The makeup is similar to the Deserialization event, [JDK-8261160](https://bugs.openjdk.java.net/browse/JDK-8261160).)
>
> The event's only datum (beyond those common to all jfr events) is the class of the object that was finalized.
>
> The Category for the event:
> `"Java Virtual Machine" / "GC" / "Finalization"`
> is what made sense to me, even though the event is generated from library code.
>
> Along with the new regtest, I added a run mode to the basic finalizer test to enable jfr.
> Automated testing looks good so far.
>
> Thanks,
> -Brent
