> The actual arguments check is wrong, as it's never printing the message of the correct usage. So, running the code with a wrong number of parameters we get the exception:
> yarn jar /var/tmp/WordCount.jar task0.WordCount2
> Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
> at java.util.ArrayList.rangeCheck(ArrayList.java:635)

> Intead than the expected message
