It looks like you add <group> on hazelcast-local-config.xml, if you want to upgrade to hazelcast-5.3.7.jar, that is a invalid configuration now.
5.3.7 use <cluster-name> instead of <group><name>SOME-NAME</name></group>, and I had hard code cluster as openfire-cluster-by-hazelcast on hazelcast-cache-config.xml, see https://github.com/igniterealtime/openfire-hazelcast-plugin/blob/main/classes/hazelcast-cache-config.xml

You can also get some information from the legacy code: https://github.com/hazelcast/hazelcast/blob/v3.12.5/hazelcast/src/main/java/com/hazelcast/config/GroupConfig.java

Correct. I had already mentioned this in the readme of version 3.0.0 of the plugin, and in the release notes.
