...vax.xml.bind.DatatypeConverter.parseHexBinary(hexString) seems to be about 20% faster than the above solution in my micro tests (for whatever little they are worth), as well as correctly throwing exceptions on invalid input (e.g. "gg" is not a valid hexString but will return -77 using the solution a...
