This seems to an oddity with ByteArrayInputStream as calling 
InputStream.read with a zero length byte array should return 0. If you 
invoke a channel's read method with a buffer that has zero bytes 
remaining then it should return 0, it can't from the channel (or the 
underlying input stream in this case) because there is nowhere to put 
any bytes that is reads.
