> Key: QPID-8212
> URL: https://issues.apache.org/jira/browse/QPID-8212
> Project: Qpid
> Issue Type: Bug
> Components: JMS AMQP 0-x
> Affects Versions: qpid-java-client-0-x-6.3.1
> Reporter: Alex Rudyy
> Priority: Blocker
> Fix For: qpid-java-client-0-x-6.3.2
>
>
> When method {{MessageConsumer#close()}} is invoked in one thread and method {{Connection#close()}} is invoked in another thread, the incoming {{BasicCancelOk}} frame can be ignored due to {{Connection#_closed}} flag being set. As result, the call to {{MessageConsumer#close()}} can block for 60 seconds and end up in exception due to not being able to receive {{BasicCancelOk}}. Invocation of {{Connection#close()}} also gets blocked due to message delivery lock being hold on consumer close.
> The defect was introduced as part of changes made against QPID-8185 in commit
> [f89f6c2f45d11fc63551d0d61c17eceedd6bd247|https://git-wip-us.apache.org/repos/asf?p=qpid-jms-amqp-0-x.git;h=f89f6c2]
> Method {{AMQProtocolSession#isClosedForInput}} checks whether session is closed for input by calling {{AMQSession#isClosed()}}. The latter returns true when either {{AMQSession#_closed}} or {{AMQConnection#_closed}} holds {{true}}. Only {{AMQSession#_closed}} should be checked in {{AMQProtocolSession#isClosedForInput}}.
