java 5 -- are you sure it isn't nonsense?

protected SortedSet<ScoredRef<Topic,SyndEntry>> entries = new TreeSet<ScoredRef<Topic,SyndEntry>>();

Java 5 may very well be nonsense. SyndEntry was originally Entry<Syndication,SimpleEntryBody<UTF8Encoding>> or similar but that reduced everything to some sort of pointier version of LISP.
