Does anybody know how to make Observable.error(CustomException()) or even throw CustomException() work in Kotlin? RxJava is having trouble propagating the error due to it not being a checked exception I think:

rx.exceptions.OnErrorFailedException: Error occurred when trying to propagate error to Observer.onError
