Is it possible to completely mask a password with JLine?

I'm using Spring Shell for a CLI and I want to read a password from the input line. For such purpose spring shell has jline, so using the official documentation [1] of jline it suggests the following:

public static void main(String[] args) throws IOException {
    String password = new ConsoleReader().readLine('*');
    System.out.println("My password is: "+password);
}

When starting the application it looks like this:

mysecretpassword   << entered by myself 
****************   << masking from jline
My password is: mysecretpassword  << my output

So my question is what is the purpose of masking the password if it is shown anyway, when I type it? Is there a possibility to do it Unix style and don't even show the password, while typing it?
