A new JDK Flight Recorder Event, `jdk.FinalizerStatistics`, identifies classes at runtime that use finalizers. The event is enabled by default in the JDK (in the `default.jfc` and `profile.jfc` JFR configuration files). When enabled, JFR will emit a `jdk.FinalizerStatistics` event for each instantiated class with a non-empty finalize() method. The event includes: the class that overrides `finalize()`, that class's `CodeSource`, the number of times the class's finalizer has run, and the number of objects still on the heap (not yet finalized). For information about using JFR, see the [User Guide](https://docs.oracle.com/en/java/java-components/jdk-mission-control/8/user-guide/using-jdk-flight-recorder.html#GUID-D38849B6-61C7-4ED6-A395-EA4BC32A9FD6).

If finalization has been disabled with the `--finalization=disabled` option, no `jdk.FinalizerStatistics` events are emitted.
