             Summary: TransactionProxyImpl.prepare() does not wait for async operations to complete
                 Key: IGNITE-4648
                 URL: https://issues.apache.org/jira/browse/IGNITE-4648
             Project: Ignite
          Issue Type: Bug
          Components: cache
    Affects Versions: 1.7
            Reporter: Pavel Tupitsyn
            Priority: Minor
             Fix For: 2.1


{{commit}} and {{rollback}} wait for async operations by calling {{tx.txState().awaitLastFut();}} (see {{GridCacheSharedContext}}).

There is no such thing in {{IgniteInternalTx.prepare()}} implementations.

Since {{prepare}} is an internal method, this is not an issue mostly, except for two things:
* JTA. {{CacheJtaResource}} calls {{prepare()}} explicitly. 
* .NET {{TransactionScope}} API. Same thing as JTA, basically. {{PlatformTransactions}} call {{prepare()}} as well.


As a result, if user starts an async operation within JTA transaction and then completes the tx, undefined behavior is possible.
