Description

I tried consuming the Atom feed available at http://www.snellspace.com/wp/wp-atom1.php in a Java application as below:
RestClient client = new RestClient();
//String url = "http://alexharden.org/blog/atom.xml"; //this feed can be read
String url = "http://www.snellspace.com/wp/wp-atom1.php"; //this feed cannot be read!
//but http://feedvalidator.org/ says it is a valid Atom 1.0 feed
Resource resource = client.resource(url);
AtomFeed feed = resource.accept(MediaType.APPLICATION_ATOM_XML).get(AtomFeed.class);

It however fails with the below error:
Exception in thread "main" java.lang.RuntimeException: Illegal atom content: must contain a single child element
