Niels Bertram commented on CAMEL-7351:
--------------------------------------
It also throws that exception when one configures a route with any of the
interceptors, e.g.:
{code:java}
interceptFrom("direct:start")
.process(new SomeProcessor());
from("direct:start")
.routeId("some-route")
.transacted("PROPAGATION_REQUIRED")
.to("log:me")
{code}
> NPE in CamelInternalProcessor

> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.12.2
> Environment: CamelContext executing in
> https://github.com/hawtio/hawtio-camel-wiki
> Deployed to apache-tomcat-7.0.47

> Using Trace mode in Hawtio throws NPE when route uses <onException> to handle
> a business exception. Trace mode is successful (no NPE) when the route does
> not throw a business exception (i.e. route is successful).
> I suspect that the value of routeDefinition in BacklogTracerAdvice is null
> when <onException> handles an exception.
