The PrintOopAddress code guards printing the address of an oop in printing code. When moving metadata out of permgen, we made print_address_on() not conditional on the PrintOopAddress flag. So the only thing left is printing the address of the oop in various places. So this shouldn't be a flag, I think it should be default.

Except this function in objArrayOop:

void ObjArrayKlass::oop_print_value_on(oop obj, outputStream* st) {
  assert(obj->is_objArray(), "must be objArray");
  st->print("a ");
  element_klass()->print_value_on(st);
  int len = objArrayOop(obj)->length();
  st->print("[%d] ", len);
  obj->print_address_on(st);
  if (NOT_PRODUCT(PrintOopAddress ||) PrintMiscellaneous && (WizardMode || Verbose)) {
    st->print("{");
    for (int i = 0; i < len; i++) {
      if (i > max_objArray_print_length) {
        st->print("..."); break;
      }
      st->print(" " INTPTR_FORMAT, (intptr_t)(void*)objArrayOop(obj)->obj_at(i));
    }
    st->print(" }");
  }
}

philli% grep -r max_objArray_print_length
share/vm/oops/objArrayKlass.cpp:static int max_objArray_print_length = 4;
share/vm/oops/objArrayKlass.cpp: if (i > max_objArray_print_length) {

It's got all the unregulated printing flags. I think this should just be removed. Once you have the ObjArrayOop address, you can get the elements because presumably you're in the debugger.
