title: JList - select multiple items
body: <p>I faced a problem with this <code>setSelectedValue()</code> method in <code>JList</code> when I wanted to select multiple values in a <code>JList</code> automatically, it still selected only one.  Is there a way?</p>
  
  <pre><code> String[] items = { "Item 1", "Item 2", "Item 3", "Item 4" };
        final JList theList = new JList(items);
        theList.setSelectedValue("Item 1",true);
        theList.setSelectedValue("Item 2",true);
  </code></pre>
  
  <p>This code shows only <code>Item 2</code> as selected.</p>
