[jira] [Commented] (GEODE-6195) putIfAbsent may get a returned
value caused by the same operation due to retry

Commit 9f85d83e031ad8a46267c014baea53bd8970bea0 in geode's branch refs/heads/feature/GEODE-6195b from Bruce Schuchardt
[ https://gitbox.apache.org/repos/asf?p=geode.git;h=9f85d83 ]
GEODE-6195 putIfAbsent may get a returned value caused by the same operation due to retry
Moving the check for a retried putIfAbsent to be under the RegionEntry
lock. This allows the operation to propagate throughout the cluster and
allows the client to receive a valid version tag, if concurrency checks
are enabled.
This also fixes GEODE-6630, "RedundancyLogger might throw NPE" because
tests were frequently running into that issue.

> A server which does not store the entry will try the putIfAbsent operation to host member. Currently product treats this as a failed op even though it is due to retried operation. If it does the operation on behalf of client (and client never failed over to another server), this could leads to client server data inconsistency.
