I just encountered in real Google code the expression

   md5.digest(string.getBytes())
          .toString();

...which would output something like "[B@23fc4bec", which has no relationship at all to the hash of the string.

In general, you always want to use Arrays.toString instead of array.toString(), though this particular user might have preferred e.g. hex encoding or the like.
