Exception placement in logs.

public class Main {

public static void yell(String words) {
    Objects.requireNonNull(words, () -> "Created issue" + Main.createIssue());
    System.out.printf("%s!!!!! %n", words.toUpperCase());
}

private static String createIssue() {
    System.out.println("Some external API call to bug tracker");
    return "#135345";
}

public static void main(String[] args) {
    List<String> ingredients = Arrays.asList(
            "dupa",
            "nie dupa",
            "znowu nie dupa",
            "cycki",
            null
    );

    ingredients.forEach(Main::yell);
}

}

LOGS FROM CONSOLE:

Exception in thread "main" java.lang.NullPointerException: Created issue#135345 NIE DUPA!!!!! at java.base/java.util.Objects.requireNonNull(Objects.java:347) at Main.yell(Main.java:10) at java.base/java.util.Arrays$ArrayList.forEach(Arrays.java:4389) at Main.main(Main.java:28) ZNOWU NIE DUPA!!!!! CYCKI!!!!! Some external API call to bug tracker

My question is - why excepion in logs is shown after word "DUPA!!!!!" and not below "CYCKI" where the null is?

By the way - when I copy paste logs from InteliJ console they lose formatting (everything is in single line). Is there a way to fix it?
