this might be legacy, but resultSet.getDate returns java.sql.Date instead of java.util.Date.
Seems like there might've been some implicit conversion where we don't want underneath?

Sure. I agree with you that java.sql.Date is better.
Here java.sql.Date is converted to java.util.Date because the latter is the super class of the former.

resultSet.getDate(columnIndexInResultSet, calendar);
vector.setSafe(currentIndex, date.getTime());
int day = (int) TimeUnit.MILLISECONDS.toDays(date.getTime());
if (day < 0 || day > MAX_DAY) {
throw new IllegalArgumentException("Day overflow: " + day);
