#175 java.text.ParseException: Unparseable date: "20221207T170935" in ical4j when specifying time zone Australia/Lord_Howe

[Swati Satrusalya]

I am getting a parsing exception while I am trying the following code:

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

import net.fortuna.ical4j.model.TimeZone;
import net.fortuna.ical4j.model.TimeZoneRegistry;
import net.fortuna.ical4j.model.TimeZoneRegistryFactory;
import net.fortuna.ical4j.model.property.DtStart;

public class Timezone {

    public static void main(String[] args) {


        TimeZoneRegistry registry = TimeZoneRegistryFactory.getInstance().createRegistry();
        TimeZone tz;
        LocalDateTime now = LocalDateTime.now();
        Meeting meeting = new Meeting();
        meeting.setDtStartLocal(now);
        final DateTimeFormatter ICS_DATE_FORMATTER =
                DateTimeFormatter.ofPattern("yyyyMMdd'T'HHmmss");

        //tz = registry.getTimeZone("Asia/Calcutta");
        tz = registry.getTimeZone("Australia/Lord_Howe");
        DtStart dtstart;
        try {
        dtstart = new DtStart(now.format(ICS_DATE_FORMATTER),tz);
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }    
    }
}

import java.time.LocalDateTime;

public class Meeting {
    private String meetingId;
    private LocalDateTime dtStartLocal;
    public String getMeetingId() {
        return meetingId;
    }
    public void setMeetingId(String meetingId) {
        this.meetingId = meetingId;
    }
    public LocalDateTime getDtStartLocal() {
        return dtStartLocal;
    }
    public void setDtStartLocal(LocalDateTime dtStartLocal) {
        this.dtStartLocal = dtStartLocal;
    }

I have used ical4j 3.0.19 jar and their dependency jar .

Its working for all the timezone except for the timezone "Australia/Lord_Howe".
Its only fails with summer time (DST) for timezone "Australia/Lord_Howe".

I am expecting the Dtstart value as :

DTSTART;TZID=Australia/Lord_Howe:20221207T170935
