Has anyone looked at the source for LinkedHashSet - it only overrides constructors on HashSet (or so it appears) in 1.4.0_03 and in 1.4.1_01.
How does this work? (i'm trying to figure out why using the addAll(Collection)/retainAll(Collection) are not working with a collection of a class that has overridden equals and hashcode...
I'm trying to implement union and intersect on a set and want to maintain the order in which they were added...
