Not always IMO. When I see an NPE I assume something is very wrong and that
it could be a bug in the impl OR a call site, somewhere on the code path.
With an IAE, I know for sure it's a problem in the call site (which could
be a bug of course).
I does not help that the JRE/JDK is inconsistent, so it's hard to find
examples.
