>          Issue Type: Bug
>          Components: cache

> Added test reproducing issue IgniteCacheClientMultiNodeUpdateTopologyLockTest:
> - 3 servers (node1, node2, node3), 1 client
> - client starts pessimistic tx
> - client locks key1 on node2
> - new node joins, exchanges starts, on node3 there are no ongoging cache operations and node3 sends GridDhtPartitionsSingleMessage to coordinator
> - client locks key2 on node3
> - client commits tx, when tx started on node2 finishes then node2 will send GridDhtPartitionsSingleMessage to coordinator and exchange will be completed before tx on node3 finished
> One potential fix for this issue is change exchange protocol to use two steps.
