ClassicFormat::parseObject (from DateTimeFormatter) does not conform to the javadoc and may leak DateTimeException

The Format::parseObject (which ClassicFormat implements) explicitly says that it returns `null` in case of error:

    * @return An <code>Object</code> parsed from the string. In case of error, returns null.

And it may throw NullPointerException if position is `null`:

   * @throws NullPointerException if {@code source} or {@code pos} is null.

However, ClassicFormat::parseObject does not conform to this specification and may leak DateTimeException, reproducer below:

final DateTimeFormatter formatter = new DateTimeFormatterBuilder()
            .parseCaseInsensitive()
            .append(DateTimeFormatter.ISO_LOCAL_DATE)
            .appendLiteral('T')
            .optionalStart()
            .appendValue(HOUR_OF_DAY, 2, 2, SignStyle.NOT_NEGATIVE)
            .optionalStart()
            .appendLiteral(':')
            .appendValue(MINUTE_OF_HOUR, 2, 2, SignStyle.NOT_NEGATIVE)
            .optionalStart()
            .appendLiteral(':')
            .appendValue(SECOND_OF_MINUTE, 2, 2, SignStyle.NOT_NEGATIVE)
            .optionalEnd()
            .optionalEnd()
            .optionalStart()
            .appendZoneOrOffsetId()
            .optionalEnd()
            .optionalStart()
            .appendOffset("+HHmm", "Z")
            .optionalEnd()
            .optionalEnd()
            .toFormatter(Locale.ROOT)
            .withResolverStyle(ResolverStyle.STRICT);
var object = formatter.toFormat().parseObject("2018-03-30T17-30-28.842Z", new ParsePosition(0));
assert object == null;

The snippet fails with:

java.time.DateTimeException: Value out of range: Hour[0-23], Minute[0-59], Second[0-59]
