FWIW, the API was fashioned this way since a caller might not have permission
to obtain the class loader of the class to which it wished to grant
permissions.  IIRC, I don't think there was anything intrinsically wrong with
passing in a class loader directly--there simply wasn't any use case at the
time to justify an additional method.
