I was trying to do the following, but I don't have the encoding for the string so the code below will not work (invalid output). ByteBuffer byteBuffer = ByteBuffer.wrap(byteOutputStr...
Two quotes: All of the remaining messages in the protocol take the form of <length prefix><message ID><payload>. The length prefix is a four byte big-endian value.
