> A server node may fail during the first local join exchange if thin clients
> concurrently issue *getOrCreateCache()* requests when cluster is starting.
> Dynamic cache group descriptors can become visible in *cachesRegistry* before
> the corresponding local *CacheGroupContext* is created.
> In this state, *CacheAffinitySharedManager#initCoordinatorCaches* is called
> with {*}newAff=false{*}, enters the *grp == null* branch, and tries to fetch
> affinity from a previous completed exchange. For the first local join
> exchange there is no previous exchange, which may lead to:
> {code:java}
> AssertionError: Invalid exchange futures state [cur=..., total=...]{code}
> Reproducer:
> [^ThinClientDynamicCachePressureOnRestartTest.patch]
