title: Read json array without properties with Jackson
body: <p>I'm trying to do something really simple, but I'm unable getting it right...</p>
  
  <p>Given the following json array:</p>
  
  <pre><code>["gate","","vaterlands park","","gabels gate",""]
  </code></pre>
  
  <p>I'm trying to map it using:</p>
  
  <pre><code>List&lt;String&gt; names = mapper.readValue(new URL("http://hostname/search?q=" + queryString), List.class);
  </code></pre>
  
  <p>but "names" return empty.</p>
  
  <p>Whats wrong?</p>
