Rob Godfrey updated QPID-7082:
------------------------------
    Summary: [Java Broker] Created AccessControllerContext for SystemTasks should not reference
current context  (was: [Java Broker] Closed Connection and Session objects can be leaked via
AccessControlContext object referenced from Queue#_immediateDeliveryContext)

>                 URL: https://issues.apache.org/jira/browse/QPID-7082
>             Project: Qpid
>          Issue Type: Bug
>          Components: Java Broker
>    Affects Versions: qpid-java-6.0, qpid-java-6.0.1
>            Reporter: Alex Rudyy

> Instance of AccessControlContext referenced from Queue#_immediateDeliveryContext is created
from an existing AccessControlContext on queue creation. If queue is created via messaging
layer, the existing AccessControlContext can hold references to ConnectionPrincipal and SessionPrincipal
and their connection and session object accordingly.  As result, Queue#_immediateDeliveryContext
can refer  ConnectionPrincipal and SessionPrincipa prebeting garbage collection of corresponding
AMQPConnection and AMQSessionModel objects for the duration of the queue life.
> With lots of long lived queues that were created by lots of different connections the
broker memory consumption might grow in time and eventially Broker can run OOM if not bounced.
> It seems we do not need to refer an existing AccessControlContext from any system AccessControlContext.
