About Question enthuware.ocajp.i.v7.2.1309 :

I got this question right, but just wanted you to notice that, this question is framed as

What can be inserted at //1 and //2 in the code below so that it can compile without errors:

and option 5 or e

super("unknown"); at 1 and this(nm); at 2

Is indeed a recursion, but compiles fine.

Thanks,

Have you tried it?

Sorry, You are right. It does show the compile time error.
