    Description

      SonarCloud reports that `CodeBlobIterator::_code_blob` is not initialized on shortcut path:

      ```
        CodeBlobIterator(LivenessFilter filter, T* nm = NULL)
          : _only_not_unloading(filter == only_not_unloading)
        {
          if (Filter::heaps() == NULL) {
            return; <---- here
          }
      ```

      It seems that we don't have an actual bug here, as iterator shortcuts on `_heap == _end`, but it would be cleaner to avoid garbage anyway.
