  <p><strong>Update:</strong><br>
  I found this <a href="https://forums.adobe.com/thread/108004" rel="noreferrer">post</a> and it says it uses <a href="https://timestamp.geotrust.com/tsa" rel="noreferrer">https://timestamp.geotrust.com/tsa</a> to get a timestamp. I visited this URL in the browser and received a 404 - Page not found. </p>
  
  <p><strong>Update 2:</strong><br>
  It looks like the timestamp <a href="https://forums.adobe.com/message/9052698#9052698" rel="noreferrer">site</a> has been down for a few days now.</p>
  
  <p><strong>Update 3:</strong><br>
  It looks like geotrust switched to TLS 1.2 which breaks Flash Builder. Here is Adobe's response <a href="https://forums.adobe.com/message/9052851#9052851" rel="noreferrer">here</a>:  </p>
  
  <blockquote>
    <p>Thanks for reporting the issue. We investigated and found that
    timestamp.geotrust.com has recently disabled TLS 1.0 (see comments on
    <a href="http://downornotworking.com/timestamp.geotrust.com/" rel="noreferrer">http://downornotworking.com/timestamp.geotrust.com/</a>), and hence please
    try upgrading to Java 1.8 on your machine where ADT (a component in
    AIR SDK which is based on Java) packaging takes place.</p>

  <p>OK. I've read <a href="https://discuss.as3lang.org/t/running-adobe-flash-builder-on-mac-with-java-7-and-8/453" rel="noreferrer">here</a> that there have been compatibility issues with Flash Builder and Java 1.8. Do I install Java 1.8? How do I do that with Flash Builder? </p>
  
  <p>I'm running Flash Builder 4.7 on Mac OS X 10.11</p>
