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