java.util.GregorianCalendar.computeFields() - IllegalAccessError

In an applet, the paint routine does the following:

 dat = new Date();
 cal.setTime(dat);
 cal.computeFields();

This supposedly used to work.
The setTime() method call now generates the following Error.
Which in turn hangs the awt event thread and therefore the browser.

If you are looking for the applet the source and class file are in:
