Problem

If you forget to put in the key, like this

  special-primaryMoving:
    simpleMovingProtection-enable();

instead of this

  special-primaryMoving:
    value: simpleMovingProtection-enable();

You get this

Exception in thread "main" java.lang.ClassCastException: class java.lang.String cannot be cast to class java.util.Map (java.lang.String and java.util.Map are in module java.base of loader 'bootstrap')
