Oh, so it fails the assert in the mode checker:


inline bool HeapShared::is_loading_mapping_mode() {
  assert(_heap_load_mode != HeapArchiveMode::_uninitialized, "not initialized yet"); // <---
  return _heap_load_mode == HeapArchiveMode::_mapping;
}


All right. The assert in `StringTable::shared_entry_count()` needs fixing as well then.
