Sorry, but what you provided is not even compilable ("public class A(){" -
is not a valid class declaration) and contains strange mix of TestNG and

As a more reliable way of transfer please provide an *archive* that
contains example that is *complete* (including pom.xml), *compilable* and
*runnable* without exceptions without JaCoCo.
