Running the enclosed code results in an IllegalArgumentException
being thrown from GregorianCalendar.computeTime().

Looks to be a defect in the yy->yyyy adjustment logic:
  
   - assume current century
   - parse date (calling cal.getTime())
   - if parsed date is outside century window,
     add 100 years.

This means that the calendar is being asked to
validate 29-Feb-1900, which is not valid.

Suggest yy expansion be done *before* validation, as
the year affects the valid field values.

import java.util.*;

public class LeapTest {
  public static void main(String[] args) {
    DateFormat fmt = new SimpleDateFormat("M/d/yy");
    fmt.getCalendar().setLenient(false);
    try {
      System.out.println(fmt.parse("2/29/00"));
    }
    catch(ParseException e) { e.printStackTrace(); }
  }
}
