> DataTypeUtils is used to coerce an object of one type into an object of
> another type for record-oriented data. However, the isLongTypeCompatible
> method is calling Long.parseLong and catch NumberFormatException to check if
> a String is a valid Long, instead of iterating over each character in the
> string and checking Character.isDigit. We can also use the regex defined by
> JavaDocs for Double.parseDouble to handle the case of checking if a String is
> Double-type capable.
