Details

    Description

      Copying the cached calendars in the cache in Confluence clustered results in:

      java.lang.IllegalArgumentException: Illegal property [PRODID]
at net.fortuna.ical4j.model.PropertyFactoryImpl.createProperty(PropertyFactoryImpl.java:1060)
at net.fortuna.ical4j.model.Property.copy(Property.java:524)
at net.fortuna.ical4j.model.PropertyList.<init>(PropertyList.java:76)
at net.fortuna.ical4j.model.Calendar.<init>(Calendar.java:179)
at com.atlassian.confluence.extra.calendar3.calendarstore.CalendarDataStoreCachingDecorator.copyCalendar(CalendarDataStoreCachingDecorator.java:249)
at com.atlassian.confluence.extra.calendar3.calendarstore.CalendarDataStoreCachingDecorator.getSubCalendarContent(CalendarDataStoreCachingDecorator.java:225)

      This is because the registered property/parameter factories deep inside ical4j were gone after the deserialization, and because of how java.io.Serializable was implemented, the factories weren't reregistered.
