    Description

      Though many system properties are read-only, the VM and the runtime system
      allow them to be set, sometimes with unpredictable if not disastrous results.
      We should identify precisely which system properties are read-only and disallow
      them from being set either on the command line or via the methods in the
      java.lang.System class. -- mr@eng 8/11/1998
