Parse error LocalDateTime: DateTimeParseException

When I try to parse the string "2017-04-06T21: 35: 00Z" as LocalDateTime, I get the below exception:

java.time.format.DateTimeParseException: Text '2017-04-06T21:35:00Z' could not be parsed: Unable to obtain LocalDateTime from TemporalAccessor: {InstantSeconds=1491514500, MicroOfSecond=0, MilliOfSecond=0, NanoOfSecond=0},ISO of type java.time.format.Parsed
at java.time.format.DateTimeFormatter.createError(DateTimeFormatter.java:1920) ~[na:1.8.0_91]
at java.time.format.DateTimeFormatter.parse(DateTimeFormatter.java:1855) ~[na:1.8.0_91]
at java.time.LocalDateTime.parse(LocalDateTime.java:492) ~[na:1.8.0_91]

      

        
        
        
      

    

And this is how I parse this line:

private static DateTimeFormatter formatter = DateTimeFormatter.ISO_INSTANT;
LocalDateTime time = LocalDateTime.parse("2017-04-06T21:35:00Z", formatter);

      

        
        
        
      

    

Of course, I can parse this string without using the ISO_INSTANT format, but it looks like I can also parse this string using ISO_INSTANT because of the following documentation:

 * The ISO instant formatter that formats or parses an instant in UTC,
     * such as '2011-12-03T10:15:30Z'.
     * <p>
     * This returns an immutable formatter capable of formatting and parsing
     * the ISO-8601 instant format.
     * When formatting, the second-of-minute is always output.
     * The nano-of-second outputs zero, three, six or nine digits digits as necessary.
     * When parsing, time to at least the seconds field is required.
     * Fractional seconds from zero to nine are parsed.
     * The localized decimal style is not used.

      

        
        
        
      

    

It looks to me like the string is exactly the same in ISO_INSTANT format. This is why I am wondering if the code is not working.

Sincerely.
