…saction-events is true
Batch conflation is not compatible with group-transaction-events.
It must be prevented that both are enabled at the same time for
a given gateway sender.

> WAN Conflation stats are being incorrectly incremented
> ------------------------------------------------------
>
> Key: GEODE-8302
> URL: https://issues.apache.org/jira/browse/GEODE-8302
> Project: Geode
> Issue Type: Bug
> Components: statistics, wan
> Affects Versions: 1.14.0
> Reporter: Donal Evans
> Assignee: Alberto Gomez
> Priority: Major

> When the below diff (which adds checks to confirm that conflation stats are
> not incremented in WAN tests with conflation disabled) is applied, the
> modified tests fail due to conflation stats being incorrectly incremented.
> This behaviour is only observed since the changes included in this PR were
> introduced: https://github.com/apache/geode/pull/4928
