 create multiple instances.

 The example code below shows how to build a <code>JsonArray</code> object
 that represents the following JSON array:

 <pre>
 <code>
 [
     { "type": "home", "number": "212 555-1234" },
     { "type": "fax", "number": "646 555-4567" }
 ]
 </code>
 </pre>

 <p>The following code creates the JSON array above:

 <pre>
 <code>
 JsonBuilderFactory factory = Json.createBuilderFactory(config);
 JsonArray value = factory.createArrayBuilder()
     .add(factory.createObjectBuilder()
