Console issues when typing

Hi, 

I have noticed when typing in the console some strange behavior. In the following image see how typing ("") results in ()". Is this a bug? or the console needs some additional configuration (or custom implementation) to support user input text as in the Terminal? 

This is the Java code responsible for the console output:

public class Main {

    public static void main(String[] args) throws IOException {

        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter a string: ");
        String s = br.readLine();
        System.out.println("you wrote: " + s);
    }
}
