Ralf Steppacher updated CAMEL-8904:
-----------------------------------
Description:
When using the {{netty4-http}} component as a producer, the response from the
remote server is processed in a different thread ({{... yClientTCPWorker}})
than the start of the Camel route and thus the breadcrumb ID changes (because
the MDC context changes/is lost).

In the example above the breadcrumb changes from
{{ID-ptl9921-45465-1435218175846-9-29}} to
{{ID-ptl9921-45465-1435218175846-9-33}}.
If I use http4 as the producer the breadcrumb is the same for all route steps.
Presumably because the same thread executes all route steps.
Route that reproduces the issue for me:

The {{repositoryOutboundProcessor}} and the {{onCompletion}} parts log a
different breadcrumb (and thread name) than the beginning of the route before
the {{<to uri="netty4-http:http:// ...}} step.
