> Cleaner thread will be blocked if we remove reference from ReferenceQueue
> unless the `queue.enqueue` called.
> ----
> As shown below, We call ReferenceQueue.remove() now while cleanUp, Call
> chain as follow：
> *StatisticsDataReferenceCleaner#queue.remove() ->
> ReferenceQueue.remove(0) -> lock.wait(0)*
> But, lock.notifyAll is called when queue.enqueue only, so Cleaner thread
> will be blocked.
