Sebb commented on TEXT-88:
--------------------------
No, that's not what I was suggesting.
I think null should be treated the same as a missing parameter. That is a
common API behaviour.
It's also the current behaviour.
The following are - and should remain - equivalent:
WordUtils.capitalizeFully(string)
WordUtils.capitalizeFully(string, null)
These both assume whitespace delimiters.
> WordUtils.capitalizeFully behaves in a counterintuitive manner with empty
> delimiter array.

> As discussed in TEXT-85, it seems that
> {code:java}
> WordUtils.capitalizeFully("i am fine", new char[]{}) // --> i am fine
> {code}
> Both Sebb and Arun think that this is odd and that the letter "i" should have
> been capitalized resulting in the output {{I am fine}}
