Good, thank you!

As far as I understand, if you are checking the argument, then it means
you are being handed over the object instance, then somebody already did
the instantiation, which means the class representing the object is
already initialized.

I think getClass() is just a trick employed in the absence of
Objects.requireNonNull.

Thanks,
