[LANG] Method to return random byte array?

[Duncan Jones]

Hi,

A piece of code I write far too often is:

======
public static byte[] getRandomBytes(int length) {
  // validate length is non-negative

  byte[] result = new byte[length];
  RANDOM.nextBytes(result);
  return result;
}
======

Is there a place for something like this in Commons Lang? Or, better,
does this already exist in another commons project?
