Look at the comments for startDay and endDay field in
java/util/SimpleTimeZone.java:

    /**
* This field has two possible interpretations:
+-> * <dl>
| * <dt><code>startMode == DOW_IN_MONTH</code></dt>
| * <dd>
| * <code>startDay</code> indicates the day of the month of
| * <code>startMonth</code> on which daylight
| * saving time starts, from 1 to 28, 30, or 31, depending on the
| * <code>startMonth</code>.
| * </dd>
| * <dt><code>startMode != DOW_IN_MONTH</code></dt>
| * <dd>
| * <code>startDay</code> indicates which <code>startDayOfWeek</code> in th
| * month <code>startMonth</code> daylight
| * saving time starts on. For example, a value of +1 and a
| * <code>startDayOfWeek</code> of <code>Calendar.SUNDAY</code> indicates the
| * first Sunday of <code>startMonth</code>. Likewise, +2 would indicate the
| * second Sunday, and -1 the last Sunday. A value of 0 is illegal.
| * </dd>
+-> * </ul>
* <p>If <code>useDaylight</code> is false, this value is ignored.
* @serial

    private int startDay;

Each <dl> tag is closed with </ul>, not </dl> so the view of API doc below
startDay and endDay fields are out of alignment.
See around startDay and endDay fields: http://java.sun.com/j2se/1.5.0/docs/api/serialized-form.html#java.util.SimpleTimeZone
These nestings after botn fields are inappropriate.
