10/04/2019, 10:53 AMWhen an exception is thrown but not caught by a child-Coroutine in a scope with a supervisor job (SupervisorScope), its other child Coroutines keep running and the scope remains active.
Using a 'regular' scope with a CEH or not, the scope its Job and all its child-Coroutines will finish when one of its child-Coroutines throws but not catch an exception.
