Alexey Goncharuk commented on IGNITE-9550:
------------------------------------------

The issue is caused by a race between 
{{tx.shared().exchange().readyAffinityVersion()}} and 
{{ctx.shared().exchange().lastFinishedFuture().topologyVersion()}}.

As a result, a get request which is mapped on topology version {{N+1}} is 
validated with exchange future of topology version {{N}}, thus return {{null}} 
instead of throwing an exception.

As a solution, I suggest to get rid of a separate field for 
{{readyAffinityVersion()}} and always use the latest exchange future.

> Get operation returns null for a lost partition with READ_SAFE policy
