Carl,
How did you generate the keys for your Hazelcast settings?
Also, do you have all of your nodes listed in the
'cas.ticket.registry.hazelcast.cluster.members' property, including the
localhost IP? I synchronize my properties b/w servers so the ability to
have the IPs of all servers here would be beneficial.
Thanks!
