Title: The Extension file contains the wrong class. 

This is causing the extension's dependency loader to not instantiate properly. The immediately noticed error is when parsing the config.yml, with the custom configuration given, this error is seen: There is no extension able to load the configuration for "fos_advanced_encoder". Changing the class name to match the file name fixes the problem.
