Using existing RxJava features we can reduce some code.
Also there are some style/genrics warnings.
Modifications
Custom class ObservableIO replaced by an existing RxJavaString library that provides stream reading as Observables.
Custom class PrintSubscriber replaced by Observable.doOnNext()
Removed the "unchecked assignment generic" warning for Subscriber
Removed some other warnings/style issues.
PS: @yschimke I am not sure whether you intentionally did not use these RxJava constructs or you were unaware. So, feel free to reject the changes 😄
