Unfortunately it's a third party library that uses class loader for getting a class and I cannot change it to use ActorSystem's classloader. I know Akka microkernal is deprecated but replacing it is not an option for now.
For now I'm just modifying start scripts for adding one more class path to AKKA_CLASSPATH as a fix.
