The second bug in your code is in this line:
{code}
channel.send(new Message(null, fileByte, 0, fileByte.length));
{code}

This will read the last line that is less than 128 bytes incorrectly. The correct line should be
{code}
channel.send(new Message(null, fileByte, 0, bytesRead));
{code}

I attached the correct version, you need to change the file paths.

Note that I used JGroups _master_ not 3.6.x, but the change to get it to run on 3.6.x is minimal.
