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

Comments
EVALUATION This should be done, but careful thought and possibly some API changes are required. It's too late for 1.2. -- mr@eng 9/3/1998
