> scenario:
> From a client for two concurrent transactions on a single key.
> At the same time, the GridNearTxFinishRequest message is blocked from the client, a partial network failure is emulated, as a result, one of the transactions is not completed even if the node is no longer working
> Reproducer:
> (insert this test into *TxRollbackOnTimeoutTest*)
> {code:java}
>     /**
