title: RESTEasy - simple string array/collection marshalling
body: <p>Is there a simple way for marshalling and unmarshalling String[] or List in RESTEasy?</p>
  
  <p>My code sample :</p>
  
  <pre><code>@GET
  @Path("/getSomething")
  @Produces(MediaType.APPLICATION_JSON)
  public List&lt;String&gt; getSomeData() {
      return Arrays.asList("a","b","c","d");
  
  }
  </code></pre>
  
  <p>Above gives me an Exception : </p>
  
  <pre><code>Could not find MessageBodyWriter for response object 
  of type: java.util.Arrays$ArrayList of media type: application/json
  </code></pre>
