Precondition Violations (3)
Row |
Violation |
1 | Unmatched statement Path result=(Path)super.clone(); 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 |
2 | Unmatched return p; |
3 | Unmatched return result; |
