Well, I can't answer for anyone else, but I know that I don't "have knowledge of all packages"... not even close. And also, why would I want to? I just need to know what I need, what everything else is (at a high level), and where to look it up when needed.

I agree with Henry that you definitely don't need to know all the packages! I don't either. That wouldn't be a good use of time.

There are over 200 packages in Java SE 8 (listed here). As a developer, you use open source packages more than over 75% of those on this list.
 
It is sorta covered in the JavaRanch Style Guide.
