----------------------------------------------
Summary: 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
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:
