> Consider a situation, when you have a cache with {{CacheStore}} and {{readThrough}} configured.
> One may expect, that {{IgniteCache#get(...)}} operation will never return {{null}} for
keys, that are present in the underlying {{CacheStore}}. But actually it's possible to get
{{null}} in case if remove operation is called on the same key while {{CacheStore#load}} is
running.
> Reproducer is attached.
