Row | Violation |
---|---|
1 | Unmatched statement op.finish(); 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 |
2 | Unmatched statement instance=new Config(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
3 | Unmatched statement instance=new Config(); 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 unregister(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
5 | Unmatched statement boss.operationFinished(op,this); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
6 | The refactoring of the clones is infeasible, because classes org.columba.core.command.Worker and org.columba.calendar.config.Config do not have a common superclass |
