title: how to access the resource bundle properties file directly with filename.property()
body: <p>I found a strange way to access the resource bundle properties. Here they are:  </p>
  
  <ol>
  <li>Project View:<a href="https://i.stack.imgur.com/yhLGd.png" rel="nofollow noreferrer">enter image description here</a>  </li>
  <li>Messages.properites:<a href="https://i.stack.imgur.com/Z6ov2.png" rel="nofollow noreferrer">enter image description here</a>  </li>
  <li>Get property: <a href="https://i.stack.imgur.com/luVcW.png" rel="nofollow noreferrer">enter image description here</a>  </li>
  </ol>
