Compatibility mode: modules

I've tried to run the server in compatibility mode, but haven't included the JAR with class uploaded by HotRod client - and boom, I got ClassNotFoundExceptions.

To resolve this, I've modified modules.xml for infinispan-commons and added the JAR with my classes there, but I don't think this is a correct solution - nor creating a new module and adding this as dependency to infinispan-commons. IMO I am using Infinispan as service, therefore, I should not put application classes as dependencies into modules.

The recommended approach is not described neither in User Guide nor Server Guide - these specify just the configuration option.
