Otto does not check inherited classes for methods which could be annotated with a `@Subscribe` annotation. Example: ``` java public class BaseClass{ @Subscribe public void receiveEvent(MyEvent e){ /* ... */ } } public class MainClass extends BaseClass{ /* receiveEvent is not seen by register, even if register is called in BaseClass */ } ``` Use case for this is for a project I am working on, I want SnackBar notifications to appear on any activity when a certain event is received.
