[jira] Created: (MATH-403) Never propagate a "NullPointerException" resulting from bad usage of the API

Never propagate a "NullPointerException" resulting from bad usage of the API
----------------------------------------------------------------------------

                 Key: MATH-403
                 URL: https://issues.apache.org/jira/browse/MATH-403
             Project: Commons Math
          Issue Type: Task
            Reporter: Gilles
            Priority: Minor
             Fix For: 3.0


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?
