Fallback exception returned by camel 2.12

Hi,

My camel route testing Drools + Camel works fine with Camel 2.10 but when I
use Camel 2.12.x, I get this exception :

17:15:42.148 [main] DEBUG o.a.c.i.RouteService - Shutting down child
service on route: testRoute -> Pipeline[[Channel[BeanProcessor[bean:
personHelper]],

Channel[Log(Bar)[Person ${body.name} can go to the bar]]], otherwise:
Channel[Log(Home)[Person ${body.name} is staying home]]}]]]
17:15:42.149 [main] WARN o.a.c.s.SpringCamelContext - Error occurred while
shutting down service: org.apache.camel.impl.RouteService [ at ] 5617ade8. This
exception will be ignored.

What could be the reason ?
