--------------------------------
Assignee: Keith Wall
> [Broker-J] [AMQP 0-10] Queue browsers erroneously increment the delivery count
> ------------------------------------------------------------------------------
>
> Key: QPID-8098
> URL: https://issues.apache.org/jira/browse/QPID-8098
> Project: Qpid
> Issue Type: Bug
> Components: Broker-J
> Affects Versions: 0.30, 0.32, qpid-java-6.0, qpid-java-6.1,
> qpid-java-broker-7.0.0
> Reporter: Keith Wall
> Assignee: Keith Wall
> Priority: Major
> Fix For: qpid-java-broker-7.0.2, qpid-java-broker-7.1.0
>
>
> On the AMQP 0-10 protocol path within the Broker, deliveries to queue
> browsers erroneously increase the {{MessageInstance#deliveryCount}}. This
> should not happen. The purpose of the delivery count is to count deliveries
> to (destructive) consumers - not browsers. The problem is restricted to AMQP
> 0-10 implementation. Neither AMQP 0-x nor AMQP 1.0 are affected by this
> defect.
> The defect could mean that messages are spuriously routed to a DLQ (if
> configured). For this to happen, there would need to be additional
> destructive consumers on the queue that cause the message to be 'released'.
> Releasing occurs during transaction rollback and client disconnection (when
> messages are prefetched). The message would be prematurely routed to the
> DLQ in this case.
> The defect is longstanding. I tested as far back as 0.30.
