Sebb commented on TEXT-88:
--------------------------
I would be OK with throwing NPE or IAE if the second parameter is null.
I am not OK with treating an empty delimiter array as meaning the same as an
omitted or null second parameter.
> WordUtils.capitalizeFully behaves in a counterintuitive manner with empty
> delimiter array.

> Issue Type: Bug

> 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}}
