    Preondition Violations
    Unmatched statement runSQL(session,stmt); cannot be moved before or after the extracted code, because it has dependencies to/from statements that will be extracted
    Unmatched statement runSQL(session,stmt); 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
