A side effect here is that listeners accepting Object (e.g. ApplicationListener<AfterSaveEvent<Object>>) no longer match any subtype because of the refined type matching. Instead, these listeners need to be defined as ApplicationListener<AfterSaveEvent<? extends Object>> which is actually the correct version according to generics.
