Objectify 4 : load command chain on unregistered entity throws NullPointerException

[Salomon BRYS]

Hi there,
Using Objectify 4, I have written this line of code :

MyModel model = ofy.load().type(MyModel.class).id(42).get();

And simply forgot to register MyModel with ObjectifyService.register(MyModel.class);

Objectify 3 used to throw an exception like "Class MyModel has not been registered" or something like that but Objectify 4 throws a NullPointerException.

I think this is an error as NullPointerException should never been thrown by a library, libraries should throw meaningful exceptions.

Here's the full exception :

java.lang.NullPointerException

This is a bug - it will be fixed soon. Sorry about that.

Just checking to see if this bug was fixed (or will be soon)... Just ran into the same error message that has me scratching my head wondering which entity is causing the headache.
