[jira] Commented: (MATH-403) Never propagate a
"NullPointerException" resulting from bad usage of the API
[ https://issues.apache.org/jira/browse/MATH-403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13003174#comment-13003174 ]
Gilles commented on MATH-403:
-----------------------------
Discussion is ongoing on whether we should really _always_ check for "null".
For those cases where it will make the failure closer to the source of the problem (the uninitialized reference), a "checkNotNull" utility method will added in "MathUtils".

> 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?
