> Duplicated ID causes LargeMessage lost at backup
> ------------------------------------------------
>                 Key: ARTEMIS-1221
>                 URL:
>             Project: ActiveMQ Artemis
>          Issue Type: Bug
>          Components: Broker
>    Affects Versions: 1.5.5, 2.1.0
>            Reporter: Howard Gao
>            Assignee: Howard Gao
>            Priority: Major
>             Fix For: 2.2.0, 1.6.0
> When a large message is replicated to backup, a pendingID is generated when the large
message is finished. This pendingID is generated by a BatchingIDGenerator at backup.
> It is possible that a pendingID generated at backup may be a duplicate to an ID generated
at live server. 
> This can cause a problem when a large message with a messageID that is the same as another
largemessage's pendingID is replicated and stored in the backup's journal, and then a deleteRecord
for the pendingID is appended.
> If backup becomes live and loads the journal, it will drop the large message add record
because there is a deleteRecord of the same ID (even though it is a pendingID of another message).
As a result the expecting client will never get this large message.
