    Preondition Violations
    Unmatched statement sampleListener.sampleOccurred(e); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted

    conn.close();
    Preondition Violations
    Unmatched statement conn.close(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted
    Unmatched statement conn.close(); cannot be moved before or after the extracted code, because it throws exception(s) that should be caught by a try block that will be extracted
