Rob Godfrey commented on QPID-3867:
-----------------------------------
I guess my issue is that the API on AMQQueue feels fairly "unnatural"... it's
clearly bolted on to support a particular function of the MBean rather than
naturally being something the Queue would expose, and we should probably be
doing our best to simplify AMQQueue.
In that sense I feel like actually the functionality should be moved into a
third-party class (including the management of the transaction). The API on
AMQQueue should potentially just be the ability to acquire a set of messages
matching a filter. In that sense I think the change to make the subject queue
manage the transaction is suspect.
This is possibly worth a separate JIRA though.

> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.15
> Reporter: Keith Wall
> Assignee: Robbie Gemmell
> Priority: Critical
>
> AMQQueueMBean#clearQueue|moveMessages|copyMessages all leave open that
> possibility that a LocalTransaction goes uncommitted (or unrolledback) in the
> event of exception.
> This will lead to uncontrolled store growth when used with BDB as would block
> the action of the cleaner thread.
> A finally block should be used to ensure that transaction is rolled back on
> any exception.
