> Key: ARTEMIS-1220
> URL: https://issues.apache.org/jira/browse/ARTEMIS-1220
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker
> Affects Versions: 1.5.5, 2.1.0
> Reporter: Howard Gao
> Assignee: Howard Gao
> Fix For: 1.5.6, 2.2.0

>
> When a large message is being diverted, a new copy of the original message is
> created and replicated (if there is a backup) to the backup.
> In LargeServerMessageImpl.copy(long) it reuse a byte array to copy message
> body. It is possible that one block of date is read into the byte array
> before the previous read has been replicated, causing the replicated bytes to
> corrupt.
> If we make a copy of the byte array before replication, the corruption of
> data will be avoided.
