>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Message Store
>    Affects Versions: 5.9.0

> WMQ supports a HARDENBO[1] flag on the redelivery flag impl. Which persists before dispatch.
And has a corresponding performance impact.
> So we need to implement an additional journal command to persist delivery attempts and
update the counter on restart/recovery to get parity.
> This will allow the redeliverFlag to be guaranteed to flag a potential duplicate dispatch
in the event of a hard broker failure just after dispatch.
