    Expression stoppingMessage.show() cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression sock.close() cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression stoppingMessage.show() is a void method call, and thus it cannot be parameterized
