Raul Kripalani commented on CAMEL-5722:
---------------------------------------
Yep, I committed fixes on r1400729 and r1400734 on 21/10. There was also some
discussion on the mailing list regarding other cases to consider.
Claus, that's another solution, but most consumers allow for some custom logic
to execute before the route kicks in, e.g. HttpBinding and the like. The UoW
processor wouldn't account for those scenarios, or would it?

> Key: CAMEL-5722
> URL: https://issues.apache.org/jira/browse/CAMEL-5722
> Project: Camel
> Issue Type: Bug
> Components: camel-jetty
> Affects Versions: 2.8.0
> Environment: OSGi environment, Karaf 2.2.2.
> Reporter: Raul Kripalani
> Assignee: Raul Kripalani
> Priority: Critical
>
> Happens in an OSGi environment; but it is also applicable in modular servers
> that build dynamic classloaders (e.g. JBoss AS) per deployed artifacts (WAR,
> module, EAR, etc.).
> If bundles A and B are both creating camel-jetty consumers on the same TCP
> port, the consumers will share the underlying Jetty connector. Moreover, the
> Jetty connector is indeed created by the first consumer that initialises on
> that TCP port.
> Since the Camel route executes on the Jetty Connector thread, all class
> resolutions will happen against the classloader of the bundle that
> initialises first.
> This makes class resolution absolutely undeterministic and erratic. Quite a
> nasty bug IMHO.
> Perhaps this can be fixed by adding a call to
> {{Thread.setContextClassLoader()}} passing the classloader of the
> JettyHttpEndpoint, as soon as a request comes in?
