Custom Converter in Playback Mode

Question

I am trying to add custom converter ( logging.logback.SchemaNameConverter) to the backup configuration that the converter uses Http.Context. The converter is located inside the game module.

java.lang.ClassNotFoundException: logging.logback.SchemaNameConverter

From my initial diagnosis, the problem seems to be related to class loaders. The main application uses ReloadableClassLoader(v1){file:.../target/scala-2.11/classes/}classes to load the application, where, since logback uses PlayDependencyClassLoaderto load its dependencies. Since the converter class is inside the application, it was not found by the loader PlayDependencyClassLoader.
