> GrpcProducer.doStop() invokes shutdown() on the forwarder:
> [https://github.com/apache/camel/blob/main/components/camel-grpc/src/main/java/org/apache/camel/component/grpc/GrpcProducer.java#L141]
> If the GrpcStreamingExchangeForwarder has not receieved any any exchanges, then the streamObserver field will be null, and any refrence to it triggered in doCreateStream will result in a NullPointerException:
> [https://github.com/apache/camel/blob/main/components/camel-grpc/src/main/java/org/apache/camel/component/grpc/client/GrpcStreamingExchangeForwarder.java#L92-L113]
> If the streamObserver is null, then I don't see any need to run the logic in shutdown().
