 * @summary When HelloA and HelloB are copied into the dynamic archive, the Symbols
 *          for their method's names will have a different sorting order. This requires
 *          that the dumped InstanceKlass to re-sort their "methods" array and re-layout the vtables/itables.
 *          A regression test for an earlier bug in DynamicArchiveBuilder::relocate_buffer_to_target().
