Hello!
the next code throws NumberFormatException:
Date d = new Date(77, 0, 1);
System.out.println(d);
System.out.println(DateField.stringToDate(DateField.dateToString(d)));
this caused by dateToString that adds some trailing space to the string:
+ if (s.length() < DATE_LEN) {
+ StringBuffer sb = new StringBuffer(s);
+ while (sb.length() < DATE_LEN)
+ sb.insert(0, ' ');
+ s = sb.toString();
+ }
stringToDate calls Long.parseLong that throws the exception because of the spaces.
this code was checked in:

I think the right code is:
// Pad with leading zeros
if (s.length() < DATE_LEN) {
StringBuffer sb = new StringBuffer(s);
while (sb.length() < DATE_LEN)
// sb.insert(0, ' ');
sb.insert(0, '0');
s = sb.toString();
}
is it right?
