Have you double-checked that AreaInfo is able to be found by a ContextResolver? I've seen lots of situations that don't throw exceptions, but that work strangely when you have a JAXB object that is not "registered" with a @Provider. Jersey seems to be doing its best with some kind of default behavior or something.

If that's not the problem, perhaps the generic may be the problem. Could you implement a non-generic subclass of ListInfo, such as:

public class AreaListInfo extends ListInfo<AreaInfo> {}

Then return AreaListInfo instead of ListInfo<AreaInfo>. I'm not sure, but that might do the trick.
