Code is working, but errors are still present?

Learning about loops and booleans to censor certain words; I came across an error in my code despite following the code as is in the tutorial.

The error reads as follows in the console, however the loop function still functions as intended:

How old are you? 20
Your name: Dan
Your adjective huge
Your noun: jerk
That language is bad. Try again.

Your noun: nerd
That language is bad. Try again.

Your noun: nerd
That language is bad. Try again.

Your noun:

and here is the code I have written below:

import java.io.Console;

public class TreeStory {

public static void main(String[] args) {
    Console console = System.console();
    /*  Some terms:
        noun - Person, place or thing
        verb - An action
        adjective - A description used to modify or describe a noun
        Enter your amazing code here!
    */
    String ageAsString = console.readLine("How old are you?  ");
    int age = Integer.parseInt(ageAsString);
    if (age < 13) {
      // Exit code
      console.printf("Sorry you are not old enough!\n");
      System.exit(0);
    }
    String name = console.readLine("Your name:  ");
    String adjective = console.readLine("Your adjective  ");
    String noun;
    boolean isInvalidWord;
    do {
      noun = console.readLine("Your noun:  ");
      isInvalidWord = (noun.equalsIgnoreCase("dork") ||  
                       noun.equalsIgnoreCase("jerk") ||
                       noun.equalsIgnoreCase("nerd"));
      if (isInvalidWord) {
        console.printf("That language is bad.  Try again. \n\n");
      }
    } while(isInvalidWord);
    String adverb = console.readLine("Your adverb:  ");
    String verb = console.readLine("Your verb:  ");

    console.printf("My first TreeStory:\n--------------------\n");
    console.printf("%s is a %s %s. \nThey are always %s %s.", name, adjective, noun, adverb, verb);
}

}

Also after clearing the console the error still shows up and shows previous inputs as well?
