                 Key: IGNITE-3601

             Project: Ignite
          Issue Type: Bug
            Reporter: Alexei Scherbakov
             Fix For: 1.8


Read only transactions reading the same key may throw unexpected IgniteTxOptimisticCheckedException on contending commit.

We should detect what transaction is read only and not acquire any locks in what case.
