Intellij Idea scanner.nextLine() returns empty String-CodePudding

I've noticed a weird behavior in Intellij Idea Community Edition run window.

Here is my code


        Scanner scanner = new Scanner(System.in);
        var list = new ArrayList<Integer>();

        String[] arr = scanner.nextLine().split(" ");
        for (String number : arr) {
            list.add(Integer.parseInt(number));
        }

        // scanner.nextLine();

        int n = Integer.parseInt(scanner.nextLine());

When I run it with input

1 2 4 5
3

It will return empty String "" on int n = Integer.parseInt(scanner.nextLine());, unless I uncomment scanner.nextLine() on line 9. Then it works as intended and returns 3.

I have tried to run compiled code in a Terminal window and it works just fine without extra scanner.nextLine().

I am running it on Zorin OS 16.1, IntelliJ IDEA 2022.1.1 (Community Edition) from flathub.

This behavior does not occur when I try it on my Windows 11 machine.

My question is why does it occur and how to have the same behavior on all machines?

As Thomas Kläger pointed out this is a known bug in Intellij Idea 2022.1.1 . Updating to version 2022.1.2 solved the problem.
