org.apache.commons.math.exception.NullArgumentException
All conditions checks that fail due to a {@code null} argument must throwthis exception. This class is meant to signal a precondition violation ("null is an illegal argument") and so does not extend the standard {@code NullPointerException}. Proagation of {@code NullPointerException} from within Commons-Math isconstrued to be a bug. @since 2.2 @version $Revision$ $Date$
