[jira] [Created] (GEODE-8964) Entry created via putIfAbsent with null value can write incorrect data to cache

Louis R. Jacome created GEODE-8964:
--------------------------------------

             Summary: Entry created via putIfAbsent with null value can write incorrect data to cache
                 Key: GEODE-8964
                 URL: https://issues.apache.org/jira/browse/GEODE-8964
             Project: Geode
          Issue Type: Bug
            Reporter: Louis R. Jacome


In backwards compatibility testing, an error was seen wherein a putIfAbsent with a null value was being processed by a server but interrupted by a GII with the same key. The operation was subsequently enqueued in the client's HA Region Queue as an update with a null value rather than a create with a null value -- a path that's not supported -- resulting in erroneous data sometimes being written to the client cache.
