Review Comment:
Optional: I actually think here there may not be such a need for this extra
bulky check, and call to a third party library? If I'm not mistaken the
valueOf anyway throws IllegalArgumentException if it does not match a value,
and it would be pretty easy for user to find out?
not sure if it throws exception for nulls, if not we could do that I
suppose.
Just trying to reduce bulky code here if possible.
