Volumes query not returning publisher data

[GoogleCodeExporter]

What steps will reproduce the problem?

Ran the sample code (modified to include getPublisher):
  System.out.println("Query: [" + query + "]");
    List volumesList = books.volumes.list(query);
    volumesList.setLangRestrict("ar");
      System.out.println("Fields: "+volumesList.getFields());
    //volumesList.setFilter("full");

    // Execute the query.
    Volumes volumes = volumesList.execute();
    if (volumes.getTotalItems() == 0 || volumes.getItems() == null) {
      System.out.println("No matches found.");
      return;
    }

    // Output results.
    for (Volume volume : volumes.getItems()) {
      VolumeVolumeInfo volumeInfo = volume.getVolumeInfo();
      VolumeSaleInfo saleInfo = volume.getSaleInfo();
      System.out.println("==========");
      System.out.println("Url: " + volumeInfo.getInfoLink());
      // Title.
      System.out.println("Title: " + volumeInfo.getTitle());
      // Author(s).
      java.util.List<String> authors = volumeInfo.getAuthors();
      if (authors != null && !authors.isEmpty()) {
        System.out.print("Author(s): ");
        for (int i = 0; i < authors.size(); ++i) {
          System.out.print(authors.get(i));
          if (i < authors.size() - 1) {
            System.out.print(", ");
          }
        }
        System.out.println();
      }
      System.out.println("Print type: "+volumeInfo.getPrintType());
      System.out.println("Page Count: "+volumeInfo.getPageCount());
        System.out.println("Publisher: "+volumeInfo.getPublisher());

What is the expected output? What do you see instead?
volumeInfo.getPublisher() always returning null (even if book has a publisher)

What version of the product are you using? On what operating system?
google-api-services-books-v1.2.0-beta
