 The Answer is :
 
  Please use a more current (and preferably supported) configuration
  of OpenVMS Alpha and of Java -- if you can replicate this with a
  current configuration and ECOs, please then contact the customer
  support center directly.
 
  Java V1.1.8-5 is very old -- V1.4.2-3 is current, as of this writing.)
 
  Please particularly ensure you have applied the mandatory ECO kits for
  the OpenVMS release in use, and any ECO kits that are specifically
  required by the JRE; by the Java Run-time Environment.
