> NullPointerException while trying to get the Route Status on startup
> --------------------------------------------------------------------

> Key: CAMEL-11234
> URL: https://issues.apache.org/jira/browse/CAMEL-11234
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.18.2
> Environment: Spring Boot 1.5.1
> Reporter: Raul Astudillo Markoch
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 2.18.4, 2.19.1, 2.20.0

> Using a class that extends EventNotifierSupport, we advise a route by adding
> a processor in between two outputs.
> It looks like this
> from().processor().bean().processor().processor(advised),to().
> To add the adviceWith processor we listen to the routeAdded event and advice
> the route.
> While Camel is starting up there is a line (line number 2966) in the
> DefaultCamelContext that loops through the available routes for later logging
> the amount of routes started in the context. This calls for a method (
> if(this.getRouteStatus(route.getId()).isStarted()) { ) that may return null
> if there are no routes running while this is being done, so IT WILL throw a
> NullPointerException.
> Since I'm advising routes while the context is being started, the route gets
> stopped and restarted, meanwhile the aforementioned method gets called and
> BUM.... NullPointerException.
