--------------------------------
> Events do not get removed from the client queue when 1.0 clients connect to
> 1.2 servers

> Key: GEODE-3072
> URL: https://issues.apache.org/jira/browse/GEODE-3072
> Project: Geode
> Issue Type: Bug
> Components: client queues, serialization
> Reporter: Barry Oglesby
> Assignee: Barry Oglesby
> Fix For: 1.2.0

> like:
> {noformat}
> new EventID(serverConnection.getEventMemberIDByteArray(), threadId,
> sequenceId)
> {noformat}
> This causes a 38 byte membership id to be generated:
> {noformat}
> ServerConnection on port 61938 Thread 2: XXXX EventID.EventID 3
> membershipIDLength=38
> ServerConnection on port 61938 Thread 0: XXXX
> CacheClientNotifier.processDispatchedMessage eidMembershipIdLength=55
> {noformat}
> The PeriodicAck sends in a 55 byte membership id:
> {noformat}
> ServerConnection on port 61938 Thread 0: DurableHARegionQueue.setAckedEvents
> ackedEventsSize=1
> tid=ThreadId[1]; membershipIdLength=55
> {noformat}
> HARegionQueue remove calls HARegionQueue checkEventForRemoval before it
> removes an event from the queue. When the comparison is made in HARegionQueue
> checkEventForRemoval, it returns false every time. Its false because the
> input ThreadIdentifier is not the same as the one in the currDurableMap.
> Their toStrings are the same, but they are not equal because their
> membershipIDs are not equal. This is why the events aren't being removed.
> Here is some debugging that shows the difference:
> {noformat}
> DurableHARegionQueue.checkEventForRemoval
> threadId=ThreadId[192.168.2.4(client-feeder:loner):61201:70bec7a3:client-feeder;
> thread 1]; membershipIdLength=38
> DurableHARegionQueue.checkEventForRemoval
> currDurableMapKey=ThreadId[192.168.2.4(client-feeder:loner):61201:70bec7a3:client-feeder;
> thread 1]; membershipIdLength=55
> {noformat}
