converting an array of bytes to List<Byte>

Library Apache Commons Lang has ArrayUtils.toObject, which turns a primitive array to a typed object array:

int array[] = { 1, 2, 3 };
List<Integer> list = Arrays.asList(ArrayUtils.toObject(array));

For Byte[] instead of byte[] this would work:

  Byte[] array = ....
  List<Byte> list = Arrays.asList(array);

As this post suggests: the guava Bytes class can help out:

byte[] bytes = ...
List<Byte> byteList = Bytes.asList(bytes);
