Onur Karaman resolved KAFKA-4004.
---------------------------------
Resolution: Not A Bug
Okay yeah the code is doing the right thing. I missed an earlier
OutOfMemoryError called during
{code}
this.buffer = ByteBuffer.allocate(receiveSize);
{code}
MirrorMaker swallows all throwables at some point in the code, so the next time
we try to KafkaChannel.read, the buffer will be null while !size.hasRemaining().
Basically this boils down to me trying to mirror too much from too few
MirrorMakers.
> NetworkReceive.complete() should not throw NullPointerException after
> partially reading the size

> NetworkReceive.readFrom can partially read the size and not allocate a
> buffer. A following NetworkReceive.complete() should not throw a
> NullPointerException and should instead just return false.
