During concurrent starting of nodes and cache put/get operations exception occures. Moreover some threads blocked on waiting for futures completion.

[^CacheAffEarlySelfTest.java] for problem reproducing. Note, that exception reproduces not always.

It's important that each node invokes getOrCreateCache() during concurrent start up. It seems when there are concurrent attempts to start the same cache minor topology version differs for different nodes.
