The constructor cannot be called nor can it be made accessible with setAccessible().   So the constructor for java.lang.Class is essentially the Hotspot code JavaClasses::create_mirror().  This is where the PD is assigned.

Okay so this pattern of assigning the final fields in the constructor that is never called is just for appeasing the javac compiler.
