Review comment:
@markap14 You wrote 2 byte short ...but the primitive is signed, unlike
char. is that why you had to remove buffer.putShort((short) bytesRead); to
avoid an auto boxing issue ? could you instead split into a separate data frame
or is that more work than changing formats? This seems like it has the
implication of version mismatches occurring due to differing wire format.
