Hi, Tom, We have not had this Scala+Java+Clojure combination in LinkedIn test environment yet. Let's try to remove the variables one-by-one. Could you try a simple Java+Scala test app using InMemorySystemFactory and see whether it works? If yes, I would suggest that there is some classpath issue when we add Clojure in the mix. It would be helpful if you can also provide some example code, configuration, log, and stack traces to help the debugging.
