Session replication does not work for different versions of a project

xxlali Sep 5, 2016 4:36 AM

I have a standalone mode cluster environment on Wildfly-10. When I have same version of the project on each node (I have two nodes) everything works fine. But if I have version A on node1 and version B on node2 of same projects, session replication does not work.

What is the reason of this and how can I fix it?

Thanks.

The server versions need to be the same on all nodes participating in the cluster. We don't support and neither indent to support clusters with different server versions.

You can handle this to some extent by writing custom Externalizers for your custom session attributes.
wildfly/Externalizer.java at 10.0.0.Final · wildfly/wildfly · GitHub

Your externalizer code will need to handle serialization compatibility.
Externalizers are contributed via service loader (e.g. /META-INF/services/org.wildfly.clustering.marshalling.Externalizer)
