QPID-8098: [Broker-J] [AMQP 0-10] No longer unconditionally increment

>             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
>            Priority: Major
>
> 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.
