Row | Violation |
---|---|
1 | Type org.columba.core.connectionstate.ConnectionStateImpl of variable instance does not match with type java.io.File of variable currentPath |
2 | Unmatched statement currentPath=DefaultConfigDirectory.getDefaultPath(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
3 | Unmatched statement instance=new ConnectionStateImpl(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
4 | Unmatched return currentPath; |
5 | Unmatched return instance; |
6 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero |
