The `ByteBuffer` `bb` here may be used multiple times. The first time it is used, `bb` will correctly write out to the array `b`. However, the second time it is used the buffer will already be fully read so `b` will be a zero length array with nothing in it. By flipping the ByteBuffer after use, we are able to use it over and over again.
