docs: Initialize the UUID generator with the ethernet address of the server machine.<p>
  
  The ethernetAddress parameter must represent a 'standard' ethernet MAC address string
  (e.g. '00:C0:F0:3D:5B:7C').
  
  @param ethernetAddress the ethernet address of the server machine
  @throws CmsInitException in case the ethernetAddress String is not a valid ethernet address
