I'm using ical4j 1.0.6 in a project, and have encountered an issue in an events feed that I can't figure out. The exemplar VEVENT appears below in a stripped down version of its ical, sanitized to remove client data. The DTSTART attribute of the VEVENT throws an Unparseable date exception.
Any ideas from the other folks who are more familiar with the source (I've just really started looking at the source today -- never had a reason before, since ical4j works so well). The DTSTART attributes in the VTIMEZONE parse just fine, but not that in the VEVENT.
