Tested with Merlin b48 on Windows2000(Service Pack1) ja.

While reading the Demo's .jar file(Java2D, SwingSet2...etc) on win2000 ja,
following exception thrown;

To reproduce;
Run Java2Demo or SwingSet2 by the following command;
% java -jar Java2Demo.jar
     or
% java -jar SwingSet2.jar

Result: While reading .jar file, exception thrown.
