Precondition Violations (3)
Row |
Violation |
1 | Unmatched statement reg.setPattern(from); 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 statement Commandline c=(Commandline)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 |
3 | Unmatched return c; |
