ClassCastException when running v1.2.0 in cluster #43

Open guusdk opened 1 year ago

guusdk commented 1 year ago

This is likely servers having restarted the plugin without a reboot. References to the old classloader are retained in Hazelcast, causing this. Possible work-around: restart all servers in the cluster.

Not persisting a plugin-provided implementation in Hazelcast should fix it.

https://igniterealtime.atlassian.net/browse/OF-2239 introduces a new type of Cache to work around this problem, the org.jivesoftware.util.cache.SerializingCache which is available since Openfire 4.7.0.
