Review comment:
Yes, there has another way to fix this warning. Just add `synchronized`
on the `MultipleChannelsConsumer#addNewTarget`, but it has already added on
`BulkConsumePool#add` which invoke `MultipleChannelsConsumer#addNewTarget`.
IDE shows warning because the volatile filed has non-atomic operations on
this Class, the non-atomic operations should be synchronized. Or we just use
AtomicLong.
