1 | Type org.columba.core.gui.logdisplay.LogRecordList of variable instance does not match with type org.columba.api.shutdown.IShutdownManager of variable instance |
2 | Unmatched statement instance=new ShutdownManager(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
3 | Unmatched statement instance=new LogRecordList(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
4 | Unmatched return instance; |
5 | Unmatched return instance; |
6 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero |
