Hi everyone !

Consider this:

I know that it doesn't work and it shouldn't work.
What I am interested in is the mechanisms used by compiler
to resolve this problem. When you compile it, I assume that
? super Integer is changed to some kind of a class. If it
does, how is it then compared to other Objects ? The bottom line:
If ? super Integer is translated into some kind of object
which is then called by the compiler capture of ? super Integer,
how this object can be compared to lets say Object ?

Or maybe I am wrong and that's not the way compiler works here ?
If not, what is the purpose of "capture of" mechanism and
how is it used ?
