So java 1.11 has removed all of the javax.* classes, so we need a 
replacement.

The patch is fine and gives the same results, but since we are
now using java 1.8 you can do this in one line like so:

    String s = String.format("%032x", new BigInteger(1, 
digest)).substring(0, 8);

[You can add '.toUpperCase(Locale.ROOT)' if you want to preserve the 
uppercase names which I don't think is important.]
