Lorenz Quack updated QPID-7962:
-------------------------------
Attachment: 0001-QPID-7962-Broker-J-AMQP-1.0-In-some-circumstances-Br.patch
My attached patch tries to fix the issue by doing two things:
* When message is stolen from consumer add it to the queue's list of interested
consumers
* Rename {{QueueConsumer#}} and {{ConsumerTarget#queueEmpty}} to
{{#noMessagesAvailable}}. The effect of this method is potential auto-close on
0-8 and potential credit draining on 1.0. This is now always called when we
currently cannot deliver messages to this consumer. This can occur when
** there is no message (the queue is empty)
** existing messages do not pass through the consumer's filters
** the consumer has no credit
** there is a different consumer with higher priority and credit blocking
delivery to this lower priority consumer
> [Java Broker][AMQP 1.0] In some circumstances Broker fails to send Flow back
> when Flow with drain flag set is received from client
