In general, StringUtils seems to munge up the distinctions between null,
zero-length, and whitespace-only strings. Obviously there is no concrete
definition of what "empty" means. This makes the whole suite of related
methods hard to learn, IMO.
Personally, I think "empty" should mean "zero-length or whitespace-only",
but should not include null. You can't really say that your box is empty if
you have no box at all.
Another appropriate term would be "blank". Perhaps a way to fix all this
would be to deprecate the poorly-defined "empty" methods and replace them
with well-defined "blank" methods.
