There is no toString implementation for KafkaStream, so if a user tries to print the stream it falls back to default toString implementation which tries to iterate over the collection and gets stuck indefinitely as it awaits messages. KafkaStream could instead override the toString and return a verbose description of the stream with topic name etc.

println("Current stream: " + stream) // This call never returns
