You are right. My original suggestion was actually to add a varargs  
version of unmodifiableList(), etc. (see http://mail.openjdk.java.net/pipermail/coin-dev/2009-July/002097.html 
):

List<Integer> list = ArrayList.unmodifiableList(1, 2, 3);
Set<String> set = HashSet.unmodifiableSet("a", "b", "c");

But varargs constructors would be handy as well.
