> Users should be encouraged to eagerly verify that their POJOs satisfy all the requirements that Flink imposes, however we provide no convenient way to test that.
> They currently have to resort to something like below, which isn't obvious at all:
> {code:java}
> TypeSerializer<Event> eventSerializer =
>             TypeInformation.of(Event.class).createSerializer(new ExecutionConfig());
> assertThat(eventSerializer).isInstanceOf(PojoSerializer.class);{code}
