Sebb commented on LANG-1410:
----------------------------

However, in this case it would be possible to eliminate the variable entirely:

{code}
        if (cs == null) {
            return true;
        }
        for (int i = 0; i < cs.length(); i++) {
            if (!Character.isWhitespace(cs.charAt(i))) {
                return false;
            }
        }
        return true;
{code}
