Looks good, except a bit in Finalizer.printFinalizerQueue, specifically:

 122                     /* Clear stack slot containing this variable, to decrease
 123                       the chances of false retention with a conservative GC */
 124                   referent = null;

Peter already noted these lines are mis-indented.

However I’m not convinced that assignment is actually useful, since I think it can be optimized away.
