Set SelectItem not supported by RI 1.2 (IllegalArgumentException)

Question

When using a Set (TreeSet) of SelectItems to populate a h:selectOneMenu, selecting an entry in the select box results in an IllegalArgumentException:
java.lang.IllegalArgumentException
     javax.faces.component.SelectItemsIterator.next(SelectItemsIterator.java:177)

I'm migrating from Myfaces 1.1.5 to RI 1.2 (jsf-1_2_07). (Myfaces does support Set<SelectItem>...)
We use (a lot of) TreeSets with a comparator to be shure that our selectOneMenus are sorted.
It seems to me that adding something like the following code to the next() method of javax.faces.component.SelectItemsIterator would do the trick:
            } else if (value instanceof Set) {
                items = TypedCollections.dynamicallyCastSet((Set) value, SelectItem.class).iterator();
                return (next());Is there a workaround or can this be fixed?

Fix checked in which will be available in tonight's nightly [1], and ultimately will be in 1.2_08.
