> I think we do not need null check here:
> [https://github.com/apache/beam/blob/master/runners/java-fn-execution/src/main/java/org/apache/beam/runners/fnexecution/control/FnApiControlClient.java#L151]
> Because before the the `onNext` call, the `Future` already put into the queue
> in `handle` method.
>
> I found the test as follows:
> {code:java}
> @Test
> public void testUnknownResponseIgnored() throws Exception{code}
> I do not know why we need test this case? I think it would be better if we
> throw the Exception for an UnknownResponse, otherwise, this may hidden a
> potential bug.
> Please correct me if there anything I misunderstand @kennknowles
