-------------------------------
Assignee: Eric Shu
> Region.values() doesn't work properly inside JTA
> ------------------------------------------------
>
> Key: GEODE-2349
> URL: https://issues.apache.org/jira/browse/GEODE-2349
> Project: Geode
> Issue Type: Bug
> Components: transactions
> Reporter: Vadim Lotarev
> Assignee: Eric Shu
> Priority: Major
>
> I experienced rather strange error invoking Region.values() within JTA
> transaction: {{java.lang.IllegalStateException: The Region collection is not
> transactional but is being used in a transaction}}.
> Doing some investigation I think I understand what is the cause of this
> error. Everything works if {{Region.values()}} invoked alone in transaction
> but failed if you invoke, say, {{get()}} on another (or the same) region
> before starting iteration over the collection returned by {{values()}}. I
> think that the reason of this error is the absence of {{discoverJTA()}} in
> {{values()}} method. So, when {{values()}} invoked first time {{EntriesSet}}
> is created with {{myTX = null}} since no transaction is determined (as soon
> as {{discoverJTA()}} is not invoked). If you are iterating immediately
> everything works as soon as there are no transaction on a region still
> ({{EntriesSet.myTx = null && topRegion.isTX() = false}}). But as soon as you
> invoke {{get()}} (or any other method where {{discoverJTA()}} is invoked)
> than all regions became transactional and next execution of
> {{EntriesSet.iterator()}} failed ({{EntriesSet.myTx = null &&
> topRegion.isTX() = true}}).
