>            Reporter: Aditya Kishore

> The attached patch addresses few issues.
> # We need only (3*this.length) capacity in ByteBuffer and not (3*this.bytes.length).
> # Do not calculate (offset + length) at every iteration.
> # No test is required at every iteration to add space (' ') before every byte other than
the first one. Uses {{sb.substring(1)}} instead.
> # Finally and most importantly (the original issue of this report), downcast the promoted
int (the parameter to {{Integer.toHexString()}}) to byte range.
> Without #4, the byte array \{54,125,64, -1, -45\} is transformed to "36 7d 40 ffffffff
ffffffd3" instead of "36 7d 40 ff d3".
