Your argument being that the JDK and others do NPE when null? i.e. NPE

Yes. Some things to note:
* The JDK does this as their pattern
* JDK 7 definitely encodes this patter in their new Object.notNull() method.
* Google Collections -- being a JDK wannabe addition -- does this
* Josuha Bloch's "Effective Java" (two editions) has codified this
expectation into the minds of developers.
+1 to NPE.
While I know this is the modern advice, there will be other places where
any NPE is a bug, and thus Validate should throw IAE.
There are no pretty solutions
- two classes ValidateNPE and ValidateIAE?
- some kind of static flag?
- picking one, and offending the others?
