Subject Re: Graceful shutdown and individual routes

Hi

You can use the in flight registry to see if there is any message
ongoing in your route.
And then wait until there are no more before stopping.

But we could probably also add support for graceful shutdown on
individual routes, leveraging the existing logic in Camel.
Could you create a JIRA ticket?
