Review Comment:
The point is not to test whether the CNFE is thrown, but to make sure the
test code is dynamically loading the class specified. We wouldn't have had a
way of distinguishing between SystemPropertiesCredentialProvider being loaded
and any other provider being loaded. The new tests added are better in that
they check (in the error message) that the class we wanted was actually loaded.
