RFR (S) 8175249: VMThread::run fails in VerifyBeforeExit : Universe::verify

Hi Coleen,

  233       }
  234       if (probe->pd_set() == current) {
  235         probe->set_pd_set(current->next());
  236       }
  237       ProtectionDomainEntry* to_delete = current;
  238       current = current->next();
  239       delete to_delete;
  240     } else {
  241       current = current->next();
  242     }

when probe->pd_set() != current, I think you need prev->_next = 
current->_next to keep linked list valid.

Do I miss something here?

Thanks,

-Zhengyu
