Java LocalDateTime Formatter Issue

Question

I am currently working with Java LocalDateTime Formatters where i want to parse an Date from a String. I boid the problem down to the following code. This is using the Formatter correctly to create a String of this pattern, but it is not able to read the exact same String. And i have problems to find out why that is so.

    public static void main(String args[]) {
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMddHHmmssSSS");
        String stringTime = LocalDateTime.now().format(formatter);
        System.out.println(stringTime);
        LocalDateTime dateTime = LocalDateTime.parse(stringTime, formatter);
        System.out.println(dateTime);
    }

What makes this even more confusing for me, if i insert a caracter in the pattern like in the code below the function works and translates a date to a string and back.

    public static void main(String args[]) {
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMddHHmm-ssSSS");
        String stringTime = LocalDateTime.now().format(formatter);
        System.out.println(stringTime);
        LocalDateTime dateTime = LocalDateTime.parse(stringTime, formatter);
        System.out.println(dateTime);
    }

I get the following stacktrace

Exception in thread "main" java.time.format.DateTimeParseException: Text '20220421154548090' could not be parsed at index 0 at java.time.format.DateTimeFormatter.parseResolved0(DateTimeFormatter.java:1949) at java.time.format.DateTimeFormatter.parse(DateTimeFormatter.java:1851) at java.time.LocalDateTime.parse(LocalDateTime.java:492)

I would be very glad for some advice here.

After the request from @deHaar I tryed different Java- Versions. With zulu-8 this issue is appearing, with higher Versions like zulu-17 the code works just fine. So I'll have to use a higher version or find a workaround. Thank you for your replys.
