While perhaps a nice example in isolation, creating a lambda when
there's already a specialized convenience class available expressing the
same thing doesn't add any value.

I chose to go with keeping names in line with existing methods. If
anything is to be done about this I'd prefer changing all names in the
class to be consistent and modern, and that'd be a separate RFE.

The call to Integer.getInteger on line 143 was supposed to be without
the defaultVal param to avoid always boxing the defaultVal. Fixed in-place.
