Basically what I want to do is to replicate custom Spring ApplicationEvent instances between nodes of a cluster hosting my Spring webapp.
Right now I only use Tomcat's HTTP session replication, nothing else.
On the documentation page of Terracotta, I can see following:
"Clustering Spring Events is not supported in Terracotta 3.1 and later. If you have a requirement to cluster Spring Events, bring your questions to the Terracotta Forums for help."
