/**
* Cleanup Mockito's Thread Local state that leaks memory
* Mockito.reset method should be called at the end of a test in the same thread where the methods were
* mocked/stubbed. There are some tests which mock methods in the ForkJoinPool thread and these leak memory.
* This listener doesn't support parallel execution at TestNG level. This is not thread safe.
* Separate forks {@code testForkCount > 1} controlled with Maven Surefire is the recommended solution
* for parallel test execution and that is fine.
