> Key: CAMEL-26001
> URL: https://issues.apache.org/jira/browse/CAMEL-26001
> Project: Camel
> Issue Type: Bug
> Affects Versions: 4.18.0, 4.22.0, 4.23.0
> Reporter: Claus Ibsen

> The ical data format converts the body with {{convertTo(Calendar.class,
> graph)}} ({{ICalDataFormat}}, main 50d17f9c2614, line 48), not
> {{mandatoryConvertTo}}. There is no type converter to {{Calendar}}, so any
> other body, for example the iCalendar text, becomes null. ical4j then fails
> with {{NullPointerException: Cannot invoke
> "net.fortuna.ical4j.model.Calendar.toString()" because "calendar" is null}},
> which does not say that the body is not a Calendar.
> Checked on 4.24.0-SNAPSHOT with {{camel run}}: {{marshal: ical}} of the text
> of a {{.ics}} file gives that NullPointerException, while the {{Calendar}}
> that {{unmarshal: ical}} gives is marshalled.
> *Proposed change*: use {{mandatoryConvertTo}}, so the error says that no type
> converter makes a {{Calendar}} of the body.
