> This class is usually preferable to AtomicLong when multiple threads
update a common sum that is used for purposes such as collecting statistics,
not for fine-grained synchronization control. Under low update contention, the
two classes have similar characteristics.
Are these use cases, that have been modified, meet this criteria?
