Javen, Just for clarity, by persistent collections, are you talking about _functional_ persistent collections (a la Scala, Clojure and Haskell), _disk_-persisted collections, or some other definition of "persistent"?

Properties is a persistent hashtable. SortedProperties is a persistent TreeMap. Unless you're thinking about a new family of SortedProperties. Were you thinking about letting the user provide the Map implementation and the SortedProperties would handle the persistence? For example, if I wanted to persist a MultiValuedMap or a BidiMap, could I do that? new PersistentMap<MultiValuedMap<K, V>>(); new PersistentMap<CaseInsensitiveKeyedMap<String, Object>>(); Is there a real scenario where this would be needed?
