If we had had a stronger type system that would allow you to say that 'this parameter may never be null, and you compiler please check that at every call, by doing static analysis of the code'. Then we could have stamped out classes of bugs.

Hum, it may be true that about 50% of bugs encountered are null pointer 
exceptions, but certainly 50% is not the percentage of the effort/time 
spent in debugging NPEs, as generally, NPEs are very easy to detect and 
to fix. As a very rough estimate, I'd say such effort is about 5%-20%.

So, although I wouldn't say no to a non-nullable types feature, I don't 
think it would have that much of an impact.
