> IgniteCache#size() call may be made while the Cache Affinity Version change,
> that follows the completion of rebalance, is still in process. It can lead
> to the situation when some nodes calculate the local cache size based on the
> updated Affinity version, while others relies on the old one. As a result,
> the IgniteCache#size() value will not match the expected value.
