> Package "exception" contains a class named "NullArgumentException" meant to signal that an argument was "null" where it shouldn't have been.
> For consistency, every method of the API should be checked for "null" arguments and throw "NullArgumentException" appropriately.
> This means hunting down all unchecked uses of references. Is there a tool that will report those?
