    Description

      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.
