Is this really widening vs autoboxing?

Question

I saw this in an answer to another question, in reference to shortcomings of the Java spec:

There are more shortcomings and this is a subtle topic. Check

Answer 1

Yes it is, try it out in a test. You will see "long" printed. It is widening because Java will choose to widen the int into a long before it chooses to autobox it to an Integer, so the hello(long) method is chosen to be called.

Edit: the original post being referenced.

Further Edit: The reason the second option would print Integer is because there is no "widening" into a larger primitive as an option, so it MUST box it up, thus Integer is the only option. Furthermore, java will only autobox to the original type, so it would give a compiler error if you leave the hello(Long) and removed hello(Integer).
