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