Row | Violation |
---|---|
1 | Type org.columba.core.main.ColumbaServer of variable instance does not match with type org.columba.mail.folder.mh.MHMessageFileFilter of variable myInstance |
2 | Unmatched statement myInstance=new MHMessageFileFilter(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
3 | Unmatched statement instance=new ColumbaServer(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
4 | Unmatched statement instance=new ColumbaServer(); 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 |
5 | Unmatched return myInstance; |
6 | Unmatched return instance; |
7 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero |
