For reading date cells this method has proven to be robust so far:

private LocalDate readCellAsDate(final Row row, final int pos) {
    if (pos == -1) {
        return null;
    }
    final Cell cell = row.getCell(pos - 1);
    if (cell != null) {
        cell.setCellType(CellType.NUMERIC);
    } else {
        return null;
    }
    if (DateUtil.isCellDateFormatted(cell)) {
        try {
            return cell.getDateCellValue().toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
        } catch (final NullPointerException e) {
            logger.error(e.getMessage());
            return null;
        }
    }
    return null;
}
