    Hi Ben,

    I've been trying to import the ics files from the mozilla site (http://www.mozilla.org/projects/calendar/holidays.html) and with some of them I get exceptions. For example, the following file throws this Exception:
    net.fortuna.ical4j.data.ParserException: An error ocurred during parsing
    at net.fortuna.ical4j.data.CalendarParserImpl.parse(Unknown Source)
        at net.fortuna.ical4j.data.CalendarBuilder.build(Unknown Source)
        at net.fortuna.ical4j.data.CalendarBuilder.build(Unknown Source)
    [...]
    Caused by: java.text.ParseException: Unparseable date: " ;VALUE=DATE"
        at java.text.DateFormat.parse(DateFormat.java:335)
        at net.fortuna.ical4j.util.DateTimeFormat.parse(Unknown Source)
        at net.fortuna.ical4j.model.property.DtStart.setValue(Unknown Source)
        at net.fortuna.ical4j.data.CalendarBuilder.propertyValue(Unknown Source)
        at net.fortuna.ical4j.data.CalendarParserImpl.parseProperty(Unknown Source)
        at net.fortuna.ical4j.data.CalendarParserImpl.parsePropertyList(Unknown Source)
        at net.fortuna.ical4j.data.CalendarParserImpl.parseComponent(Unknown Source)
        at net.fortuna.ical4j.data.CalendarParserImpl.parseComponentList(Unknown Source)

    The file I'm using is this one which I think is compliant with the iCal format:

    I'm using the 0.9.11 version of iCal4j and I'm kinda lost here. It'd be great of you can find a solution.

    Cheers,

    Marcel

      Hi Marcel,

      Did you try running it with relaxed parsing enabled (i.e. -Dical4j.unfolding.relaxed=true)? See the javadocs for UnfoldingReader or the README for more info on this.

      If you have tried this, perhaps let me know which calendar files are causing problems and I will download and try them here.

      regards,
      ben

      Hi Ben!

      Thanks for that hint - it works!
