---|---|
1 | Type org.columba.mail.pgp.PGPPassChecker of variable myInstance does not match with type org.columba.api.command.IStatusObservable of variable observable |
2 | Unmatched statement observable=((IMAPRootFolder)getRootFolder()).getObservable(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
3 | Unmatched statement myInstance=new PGPPassChecker(); cannot be moved before the extracted code, because it has control dependencies from statements that will be extracted |
4 | Unmatched return observable; |
5 | Unmatched return myInstance; |
6 | The refactoring of the clones is infeasible, because the number of macthed statements is equal to zero |
