Review comment:
> If you read my first comment, it was not about that you get the value from
that counter, but I wondered why you do `getAndIncrement` instead of just `get`.
Actually, I also want to use `get` API, but `CheckpointIDCounter ` does not
provide `get` API.
> Rest of my comments still holds though, why not remove the
throwing/catching of an exception that we can also directly report to the
failure manager? I also think that makes other counts accurate because it
obtaining the id can then always happen under the lock.
OK, agree.
