> The Document for _DefaultStyledDocument.setCharacterAttribute_ states that the range of length accepted is `length - the length >= 0`, whereas in code the length check is done only for `length==0`. Meaning the control just returns if the `length` is 0. Since length is  _int_ type and there is a possibility of negative length being set through the method, the code doesn't actually handles the negative length case. Hence to handle negative length, negative length check has been added along with 0 check. Its safe to check and return the control for `negative` length input. Test case to check the same is added.
