title: Apache archiva returns http error 503
body: <p>I am using apache Archiva v. 2.2.0 under Windows Server 2012 R2, Java version 1.8.0_60 inside VirtualBox. It used to work for quite a long time before Windows autoupdate.</p>
  
  <p>After Windows autoupdate I am getting an error message when going to archiva url: HTTP ERROR: 503 . Problem accessing /. Reason: Service Unavailable, Powered by Jetty://.</p>
  
  <p>The Apache Archiva service is running. No error logs are generated. Restarting or even reinstalling of the service has no impact.</p>
  
  <p>After rolling back of Windows update I restore the normal operation of Archiva, but mysteriously, just once, i.e. stopping and restarting of Archiva will cause the same HTTP ERROR 503.  </p>
  
  <p>The log file do not indicate any problem or error cuase.</p>
  
  <p>Thank you for any tips.</p>
