classFileParser::parseClassFile()
 // reinitialize modifiers, using the InnerClasses attribute
 4255 int computed_modifiers = this_klass->compute_modifier_flags(CHECK_(nullHandle));
            this_klass->set_modifier_flags(computed_modifiers);

After this there are three calls to validate some stuff, they are using a read context.

After this is the call to


void java_lang_Class::create_mirror(KlassHandle k, Handle class_loader,
                                    Handle protection_domain, TRAPS) {

which does the same thing (both gather and set) the (same) flags already computed and set.
