title: Is it possible to clear the Netbeans output window from my application or temporarily disable all outputs?
body: <p><strong>Some background:</strong></p>
  
  <p>I've created a Swing application which uses the <a href="https://substance.dev.java.net/see.html" rel="nofollow noreferrer">Substance LaF</a> (Thanks again, Kirill!)</p>
  
  <p>Unfortunately Swing creates a panel somewhere outside the EDT thus leading to an exception message from Substance every time I start my application. By itself this exception is great, I already saved me from creating nasty multithread GUI bugs, but I often miss important outputs because the output window is already cluttered when my application does any real work.</p>
  
  <p>The easiest way would be to patch the Substance source for my personal needs, but I'd rather leave it untouched. That's why I want to know...</p>
  
  <ol>
  <li>Is it possible to clear the output window programmatically, either by calling a method from my application or something like a delayed Ant task?</li>
  <li>Alternatively, can I temporarily disable any outputs from my application, including exceptions messages?</li>
  </ol>
