Because the field is final, it has to be initialized in the constructor in Java code.  My initial patch for modifiers chose to initialize to zero but that's not quite correct.  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.
