Yes, I'm aware of that. It's just not very helpful, because most 
interesting cases and issues are not covered.

I'm questioning the idea of
   a) having Integer act as a value box for int,
   b) putting all the same requirements on value boxes;

from my experience, trying to retrofit Integer as a value box for int is 
a futile endeavor, as well as weighing down other value boxes with 
things like reference equality etc. in the way John described in his mail.

Thanks and bye,

Simon
