title: Undecorated JDialog border
body: <p>I have a question regarding the border around an undecorated <code>JDialog</code> using the <code>Metal L&amp;F</code>.</p>
  
  <p>Look at this picture to see the border that is on this window: </p>
  
  <p><img src="https://i.stack.imgur.com/nkXx1.png" alt="enter image description here"></p>
  
  <p>I'm trying to figure out how to either get rid of or change the color of the blue border around the very outside of the <code>JDialog</code>. I looked at the UI defaults for the <code>Look &amp; Feel</code> but I wasn't able to come up with any that worked for this. </p>
  
  <p>Does anybody have any ideas on how to get rid of that border?</p>
  
  <p>Thanks!</p>
