> ForceKey response processing fails with ClassCastException with Mvcc mode that causes
test hanging.
> Issue can be easily reproduced with backups > 0 and disabled rebalance. See GridCacheDhtPreloadPutGetSelfTest.testPutGetNone1().
> Also CacheLateAffinityAssignmentTest.testRandomOperations() hangs sometimes due to same
reason.
