So a Package object doesn't have to be created that is completely up to the ClassLoader that loads the class.
And yes we already stumbled into this some months ago in wicket!
Remember the i think ResourceLoading stuff where we also did give a Package object as a method parameter.
That also suddenly failed because of the null that was given in that situation. I though it had something to do with Oscar classloaders
But i can be mistaken about that.
I don't care if we give a big warning about this, but then i want to be able to do it with a string or a class
So that i do get package mounting without needing to give a Package object.

So, do you know when actually Package.getPackageName fails? I thought
it fails when the class is not loaded yet. Which can be cercumvented
by calling that class first like MyClass.getPackage().
Anyway, I'm not happy with that package behaviour either, but Strings
also suck big time because they don't refactor well. And providing a
class parameter while you need the package is imo just a lousy
contract. I'd rather put a big warning there and let users be
responsibility. Or use the string. Maybe that's best.
