Okay, I put together a working test file with a new set of client libraries 
downloaded. I was able to successfully print album titles like this:

URL feedUrl = new 
URL("https://picasaweb.google.com/data/feed/api/user/default?kind=album";);
    UserFeed userFeed = myService.getFeed(feedUrl, UserFeed.class);

    for (AlbumEntry albumEntry : userFeed.getAlbumEntries()) {
      System.out.println(albumEntry.getTitle().getPlainText());
    }

Ralph, the problem for you might be that you are calling 
UserFeed.getEntries() instead of UserFeed.getAlbumEntries() which is 
returning a base class instead of the AlbumEntry class the way you were 
expecting.

Let me know if you have more trouble here.

Thanks,
-m.e.
