Bug 270481

Writing code like:

        @ComputedProperty @Transitive(deep = true)
        static int sumPositive(Depends next, int value) {
            while (next != null && next.getValue() > 0) {
                value += next.getValue();
                next = next.getNext();
            }
            return value;
        }

- e.g. observing two properties at once (value & next) doesn't work in HTML/Java API version 1.4.
