Description

Hi, 

we are using transactional reads and setting detectReadConflicts to true to ensure Isolation, as it is described in Apache Geode documentation.

Only read operations are performed in transaction.

This is working properly for replicated region but not for partitioned region. In the case of partitioned region, when we do the transaction commit we get the following Exception:

terminate called after throwing an instance of 'apache::geode::client::Exception'
