Remove 'final' keyword from method AbstractResource#respond

I need a transactional layer between the method call newResourceResponse(attributes); and data.getWriteCallback().writeData(attributes); cause the ResourceResponse holds a transactional reference which can not be closed until the data.getWriteCallback().writeData(attributes); was called. At this moment there is no ability to do such transactional handling.

For now I have a workaround with a DelegateResource which calls a sendReseponse method inside the respond method

public void sendResponse(final ResourceResponse resourceResponse)
  {
      final AbstractResource resource = new AbstractResource()
      {

        @Override
        protected ResourceResponse newResourceResponse(final Attributes attributes)
        {
          return resourceResponse;
        }
      };

      resource.respond(attributes);
  }
