-----------------------------------------

             Summary: MVCC TX: Possible race on invokeAll operations
                 Key: IGNITE-10572
                 URL: https://issues.apache.org/jira/browse/IGNITE-10572
             Project: Ignite
          Issue Type: Bug
          Components: mvcc
            Reporter: Igor Seliverstov
            Assignee: Andrew Mashenkov


seeĀ {{GridNearTxEnlistFuture#checkResponse}} method.

1) race on result creation - two threads may see {{this.res == null}} and just set their values,
result is partially lost

2) race on success flag set - just set false flag may be overwritten by concurrent successful
response checking operation.
