Currently the code in SequenceInputStream.transferTo() contains

                if (transferred < Long.MAX_VALUE) {
                    try {
                        transferred = Math.addExact(transferred, in.transferTo(out));
                    } catch (ArithmeticException ignore) {
                        return Long.MAX_VALUE;
                    }
                }

whereas it should contain the equivalent of what is in InputStream.transferTo

            if (transferred < Long.MAX_VALUE) {
                try {
                    transferred = Math.addExact(transferred, read);
                } catch (ArithmeticException ignore) {
                    transferred = Long.MAX_VALUE;
                }
            }
