Generic Abstract Parent Class Doubles Consumer invocation Project

Actual behaviour:

Having a class extending a class with generics which has an abstract method for the consumer method, this will result in the method annotated with @Consume on the extending class to be called twice per eventbus message.

1. Start the application
2. You will notice duplicated outputs from consumer like consuming HelloEvent on HelloService: ee73ab41-6b9a-465a-967c-d264046e0cc0

Expected behaviour

Its expected that a method annotated with @ConsumeEvent is invoked only once per message.

1. Remove public abstract void consume(@NonNull T event); from GreetingService
2. Start the application
3. You will notice that the consumer is invoked only once per message
