-----------------------------------------------
Summary: NPE Upon Restart When Using Asynchronous Event
Distribution & Conflation
Key: GEODE-7079
URL: https://issues.apache.org/jira/browse/GEODE-7079
Project: Geode
Issue Type: Bug
Components: wan
Reporter: Juan José Ramos Cassella
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()}}.
