QPID-6809: [Java Broker] Handle LockConflictException during asynchronous recovery
> LockTimeoutExceptions not handled during asynchronous recovery
> --------------------------------------------------------------
>
> Key: QPID-6809
> URL: https://issues.apache.org/jira/browse/QPID-6809
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.32
> Reporter: Keith Wall
>
> A user using the Asynchronous Recovery (0.32) feature encountered the following issue during a lengthy asynchronous recovery. This suggests that the Broker is not handling JE's LockException properly. In other parts of the code, the code takes lengths to backoff/retry in the event of a locking exception.
