This is similar to but different from a previous instance of this type of issue.

This is at about line 698 in HttpResponse.

        /**
         * Returns a {@code BodyHandler<Publisher<List<ByteBuffer>>>} that creates a
         * {@link BodySubscriber BodySubscriber}{@code <Publisher<List<ByteBuffer>>>}

         *
         * <p> When the {@code HttpResponse} object is returned, the response

        public static BodyHandler<Publisher<List<ByteBuffer>>> ofPublisher() {
            return (responseInfo) -> BodySubscribers.ofPublisher();
        }

Note the {@link Publisher Publisher<List<ByteBuffer>>}
The Publisher<List<ByteBuffer>> is read as literal HTML, which is invalid.
