Has this been fixed in the ListContainer?

@Override
public Item addItemAfter(Object previousItemId, Object newItemId) throws UnsupportedOperationException {
    throw new UnsupportedOperationException("Not supported yet.");
}

I don’t remember. Check the V7 branch from the GitHub. Do you have some reason to use that API instead of using the JDKs List interface for the backing list?
