Answer 1

You are missing spring-retry on the class path. What are you using for dependency management? It should be added to the classpath automatically when using Maven or Gradle since it's a transitive dependency of spring-amqp.
Restarting the application the consume of message is running normaly.
That makes no sense; unless you have some kind of weird classloader problem.
Try running with -verbose to get logs for all the class loading.
