Description
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.
Here's the stacktrace:
