--------------------------------------
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.
