Actually, I think the problem is with your import statements:
Change them to:
import somePackage.TopLevel;
//import somePackage.TopLevel.Inner; Or delete this...

and try again.

no, that doesn't solve it...

It does. Moreover, it solves most important problem. Even when all
Inner's members are public, and both above imports holds, the compiler
complains with:

SecondLevel.java:4: somePackage.TopLevel.Inner has protected access in
somePackage.TopLevel
import somePackage.TopLevel.Inner;
^
1 error

So the above change is required to solve other problems.

After having it solved you can choose from different solutions of
accessing Inner's members (make them public, inherit using own inner
class, and the like...).

However, I don't understand why the compiler prohibits the second
import? Importing something doesn't implies any access violation on its
use, does it?

Is there some reasonable explanation for that prohibition?
