Description

"1.1L" is not a Java Number . but NumberUtils.isNumber(String) return true.

perhaps change:

            if (chars[i] == 'l'
                || chars[i] == 'L') {
                // not allowing L with an exponent
                return foundDigit && !hasExp;
            }

to:

            if (chars[i] == 'l'
                || chars[i] == 'L') {
                // not allowing L with an exponent
                return foundDigit && !hasExp && !hasDecPoint;
            }
