(More version history info about SimpleAdapterXxx-s)
Added SimpleIteratorAdapter, which is again something that's only used with DefaultObjectWrapper(2.3.22) or DefaultObjectWrapper(useAdaptersForContainers=true). This fixes the issue where an Iterator (not to be confused with Iterable), when passed to a Java method from FTL, came through as a dysfunctional SetAdapter instead of the original Iterator object.
