> I've never seen this throw an exception, but if either of these code paths ever got executed,
and the resourceName was passed as "", it should:
> if (!iterator.hasNext() && (resourceName != null) && (resourceName.charAt(0)
!= '/')) {
> if ((url == null) && (resourceName != null) && (resourceName.charAt(0)
!= '/')) {
> "".charAt(0) should throw an IndexOutOfBoundsException
