> The following combination of features cannot be safely configured when using pure Geode Java API:
> * Replicated Region.
> * Serial Gateway Sender or Serial Asynchronous Event Queue.
> * Serial Gateway Sender / Serial Asynchronous Event Queue is Persistent.
> * Conflation is Enabled for the Serial Gateway Sender / Serial Asynchronous Event Queue.
> The problem is that, after a restart, events left-over in the persistent queue begin processing before their source {{Region}} is instantiated, causing a {{NullPointerExceptions}} while executing the conflation logic.
> The {{Region}} is only required because internally we need its name, but the name itself is already stored within the actual event so it should be safe to replace {{gsEvent.getRegion().getFullPath()}} by {{gsEvent.getRegionToConflate()}} or {{gsEvent.getRegionPath()}}.
