> NumberUtils.createLong() does not handle hex numbers, but createInteger() handles hex
and octal.
> This seems odd.
> NumberUtils.createNumber() assumes that hex numbers can only be Integer.
> Again, why not handle bigger Hex numbers?
> ==
> It is trivial to fix createLong() - just use Long.decode() instead of valueOf().
> It's not clear why this was not done originally - the decode() method was added to both
Integer and Long in Java 1.2.
> Fixing createNumber() is also fairly easy - if the hex string has more than 8 digits,
use Long.
> Should we allow for leading zeros in an Integer? 
> If not, the length check is trivial.
