RFR: 8023681: Fix raw type warning caused by Sink

[Ali Ebrahimi]

you can try this.

    private static Function<?,?> CASTING_IDENTITY = i -> i;

    @SuppressWarnings("unchecked")
    private static <I, R> Function<I, R> castingIdentity() {
         return (Function<I, R>) CASTING_IDENTITY;
    }
