Potential buffer leak

OFDecoder.decode(), lines 53-58

if (dataObject == null)

{ LOGGER.warn("Translated POJO is null"); return; }

msg.getMessageBuffer().release();
out.add(dataObject);
}

If the decoded object happens to be null, we do not release the original message buffer. I am not sure if it’s used somewhere else (unlikely, that would be bad design) - if it is not, we have a potential buffer leak.
