Nightly build version can use implementations of the java.util.List
rather than having to get back the primitive array object. Makes things
easier to work with.
Returning the Object[] actually renders everything but ArrayList style
collections useless because the mapped collections and such don't know
how to update from an index. Returning the array from an ArrayList
itself isn't that big a hit, as it's backed by such an array anyways.
