> The ParallelGatewaySenderQueue.addShadowPartitionedRegionForUserPR method
> currently compares the data policy of the input region's leader region with
> the sender's persistence policy. It assumes the input region and the leader
> region have the same data policy. In this scenario, that is not the case. The
> input region is 'non_persistent_child' which is not persistent, and the
> leader region is 'persistent_parent' which is persistent. The sender is
> 'non_persistent_sender' which is not persistent. So, instead of comparing the
> data policy of 'non_persistent_child' to the sender which would succeed since
> they are both not persistent, it compares the data policy of
> 'persistent_parent' to the sender which fails since one is persistent, and
> the other is not.
