--------------------------------
Summary: Avoid leak potential for the 0-8..0-91 default queue
Key: QPID-6272
URL: https://issues.apache.org/jira/browse/QPID-6272
Project: Qpid
Issue Type: Bug
Components: Java Broker
Reporter: Keith Wall
Assignee: Keith Wall
Priority: Minor
Fix For: 0.30
AMQP 0-8..0-91 has a concept of default queue. This is the default queue to
which operations such as basic.consume apply if the client chooses not to pass
a queue argument within the command. The default queue is defined as the
queue that is most recently declared, passively or otherwise by a queue.declare
command.
There is the potential for a leak in the current implementation of AMQChannel's
default queue implementation. It retains a reference the queue that is the
default even if the queue is deleted. It would be safer if the default queue
reference is cleared if the queue is deleted (either explicitly by a
queue.delete or the side effect of the cancelling of a consumer).
