> *Description:*
> Impossibility to replay messages from retention folders due to a
> ClassCastException.
> It happens when replication ha-policy is configured and after the live role
> switch back from the backup node to the primary node:
>
> {code:java}
> java.lang.ClassCastException : class
> org.apache.activemq.artemis.core.replication.ReplicatedJournal cannot be cast
> to class org.apache.activemq.artemis.core.journal.impl.JournalImpl
> (org.apache.activemq.artemis.core.replication.ReplicatedJournal and
> org.apache.activemq.artemis.core.journal.impl.JournalImpl are in unnamed
> module of loader java.net.URLClassLoader @73d16e93){code}
>
> See attached screenshot of the Artemis console for additional details.
>
> *Configuration details:*
> * Cluster of Artemis primary/backup groups and with replication ha-policy
> (ZK)
>
> *Reproduction scenario:*
> With a brand new primary/backup group with replica :
> * Start primary and backup nodes
> * The JMX replay command works well on primary
> * Stop the primary node, backup becomes live
> * Restart the primary, it becomes live again (failback is enabled)
> * At this step, the reuse of the replay command on the primary trigger the
> ClassCastException
