        Arrays.asList("a", "b", "c").toString();
    }
}

Visual proofs (screenshots, logs, images)

Environment

Windows 10 Pro
IntelliJ IDEA 2022.1.3

Additional context

Same AbstractCollection.toString() implementation is called for this code - same error is displayed:

public class ListToStringExample {

    public void toStringList() {
        List<String> list = new ArrayList<>();
        list.add("a");
        list.add("b");
        list.add("c");
        list.toString();
    }
}
