-------------------------------------

Jason, several months have passed. Are still interested in Guava's Preconditions? Otherwise I'd go over to fix those issues.

>             Project: Maven
>          Issue Type: Bug
>    Affects Versions: 3.2.1
>            Reporter: Michael Osipov
>
> In several spots of Maven Core, IAE is thrown where an argument is null. This should be turned into {{NullPointerException}} since JDK adheres to is and the [description|http://docs.oracle.com/javase/6/docs/api/java/lang/NullPointerException.html] of this exception indicates that and Effective Java does that too.
> I possible fix version could next minor: 3.3. Is no one is opposed it could even be 3.2.2.
