### Output
The application sends 10 messages (`foo0` ... `foo9`) to a kafka topic `si.topic` (which is created if necessary).
The application sends 10 messages (`foo0` ... `foo9`) to a kafka topic `si.topic`; this must exist or the broker must be configured to auto-create topics.
It then sends a message with a `KafkaNull` payload.
It then dynamically creates a new inbound adapter for a different topic `si.new.topic` and sends 10 messages there.
The message-driven adapter receives the messages and places them in a `QueueChannel` which the application reads and
writes to stdout:
