duplicate messages on Temporary Topics in network of brokers
------------------------------------------------------------
Key: AMQ-3274
URL: https://issues.apache.org/jira/browse/AMQ-3274
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.4.2
Reporter: Arthur Naseef
Priority: Critical
Creating a network of brokers, duplicate messages are being seen on Temporary
Topics.
The network configuration used is as follows:
<networkConnectors>
<networkConnector name="nw1_queues_from_nw2"
uri="static:(tcp://127.0.0.1:60002)"
duplex="true" conduitSubscriptions="false"
dynamicOnly="true"
networkTTL="7"
suppressDuplicateQueueSubscriptions="true"
decreaseNetworkConsumerPriority="true"
bridgeTempDestinations="true"
>
<excludedDestinations>
<topic physicalName=">" />
</excludedDestinations>
</networkConnector>
<networkConnector name="nw1_topics_from_nw2"
uri="static:(tcp://127.0.0.1:60002)"
duplex="true" conduitSubscriptions="true"
dynamicOnly="true"
networkTTL="7"
suppressDuplicateQueueSubscriptions="true"
decreaseNetworkConsumerPriority="true"
bridgeTempDestinations="true"
>
<excludedDestinations>
<queue physicalName=">" />
</excludedDestinations>
</networkConnector>
</networkConnectors>
Note there are 2 duplex connections between the brokers. Changing to
non-duplex connections, the problem goes away with 2 brokers in the network,
but reappears when a 3rd broker is added.
The problem only affects temporary Topics; normal Topics work fine.
A patch will be attached. Also, a test case will be attached when it is
available.
