java.util.Date.setYear() does not recalc month, or date when going from 29-Feb-1992
(a leap year) to a non-leap year.

Steps To Reproduce
Compile and run the following code

import java.util.Date;

public class LeapYearTest
{
    public static void main(String args[])
    {
        Date d = new Date(92, 01, 29);
        System.out.println("29-Feb-92 " + d);

        d.setYear(93);
        System.out.println("Unknown Date: " + d);
    }
}
