Subject [roller] branch master updated: Fixed: sonarqube issue - Methods returns should not be invariant When a method is designed to return an invariant value, it may be poor design, but it shouldn't adversely affect the outcome of your program. However, when it happens on all paths through the logic, it is surely a bug.
