Exception when trying to parse a LocalDateTime

It’s a bug: https://bugs.openjdk.java.net/browse/JDK-8031085

The link above also provides the workaround: using a java.time.format.DateTimeFormatterBuilder with a java.time.temporal.ChronoField for the milliseconds field:

String text = "20170925142051591";
DateTimeFormatter formatter = new DateTimeFormatterBuilder()
    // date/time
    .appendPattern("yyyyMMddHHmmss")
    // milliseconds
    .appendValue(ChronoField.MILLI_OF_SECOND, 3)
    // create formatter
    .toFormatter();
// now it works
formatter.parse(text);

Unfortunately, there seems to be no way to parse this using only DateTimeFormatter.ofPattern(String).
