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?
