    Preondition Violations
    Expression _tab.closeTab() cannot be parameterized, because it has dependencies to/from statements that will be extracted
    Expression closeConnection() cannot be parameterized, because it has dependencies to/from statements that will be extracted
    • Inline private method closeConnection
    Expression _tab.closeTab() is a void method call, and thus it cannot be parameterized
    Expression closeConnection() is a void method call, and thus it cannot be parameterized
