no output after infinite while loop with hasNext() java

Question

I want to read some names from user's input and be able to print each of them on a different line, one after an other, in reverse order. Like the example below : Test Input:

Jane Kate
John
Mary Susan Paul
Boris Ann

Expected Output:

Ann
Boris
Paul
Susan
Mary
John
Kate

Problem :

• I cannot escape from the infinite loop.
• My result should be contained in the "seq" variable but not reachable outside the while loop.
• Last token "Ann" is never past through. What I tried :
• printing at each step.
• forcing the scanner cursor to move forward with .next() method in the loop It looks like the scanner is always waiting for user input.

Here is the code I wrote.

import java.util.Scanner;

class Main {
    public String inverse(String first, String second){
        return second + System.lineSeparator() + first;
    }

    public static void main(String[] args) {

        Main m = new Main();

        Scanner scanner = new Scanner(System.in);
        // start coding here
        String seq;
        seq = scanner.next();
        String second;
        while (scanner.hasNext()) {
            second = scanner.next();
            seq = m.inverse(seq, second);
            System.out.println(seq);
        }
        scanner.close();
        System.out.println(seq);
    }
}

The last printed "seq" in the while loop is almost the result I want, except that it misses Ann. Question : Do you know from where the current behavior is coming from an what do I need to change to have the expected output?
