Row | Violation |
---|---|
1 | Type org.columba.mail.gui.contact.list.HeaderItemDNDManager of variable instance does not match with type org.columba.core.config.Config of variable instance |
2 | Unmatched statement throw new RuntimeException("Must call Constructor first!"); 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 throw new RuntimeException("Must call Constructor first!"); |
4 | Unmatched statement instance=new HeaderItemDNDManager(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
5 | Unmatched statement return instance; cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
6 | Unmatched return instance; |
7 | Unmatched return instance; |
8 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero |
