Hi Antimo,

I'm a bit confused here. Where does this CNFE happens? During tests? During deployments? Somewhere else? Do I understand correctly that {{ merge.toString(true) }} prints that {{ com.google.protobuf.GeneratedMessage }} file is present?

I guess this is a classloader problem. As you are using embedded container, that protobuf class is not present on it's classpath. Any chance you can run with managed container instead (separated JVM)? Or can you provide output of dependency:tree ?
