Precondition Violations (5)
Row |
Violation |
1 | Type com.csvreader.CsvReader of variable reader does not match with type net.sourceforge.squirrel_sql.fw.util.ClassLoaderListener of variable listener |
2 | Unmatched statement listeners.add(listener); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
3 | Unmatched statement reader.close(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
4 | Unmatched return true; |
5 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero |
