Brad Johnson commented on CAMEL-9570:
-------------------------------------
Richard,
When you say you can replicate using a routebuilder are you using an annotation
for the injection? If I recall that's how I ran into the problem. That's when
I started looking at the package scanners. That may be an unrelated problem.
But as you say, if one manually injects the reference it works fine.
If I use the @BeanInject annotation I'll get a concrete implementation of the
interface I'm specifying. If I manually inject it via blueprint XML the class
will instead be shown as com.sun.proxy.$Proxy40
I was getting similar unexpected behaviors if I used @Produce or @Consume
annotations. So there appears to be a fundamental difference in the way the
references are being handled in annotation processing versus straight XML.

> Key: CAMEL-9570
> URL: https://issues.apache.org/jira/browse/CAMEL-9570
> Project: Camel
> Issue Type: Bug
> Components: camel-blueprint, camel-core
> Affects Versions: 2.16.2
> Reporter: Quinn Stevenson
> Assignee: Christian Schneider
>
> Basic Conditions:
> - Java interface used for OSGi Services
> - Implementation of the Java interface registered as a OSGi service. Note
> that the package containing implementation is NOT exported
> - A Java RouteBuilder that uses the Java interface via bean(...) DSL calls,
> with a setter for the bean implementing the interface
> - Wire everything together with Blueprint - create a <reference ...> for the
> service, a <bean ...> for the RouteBuilder and inject the service reference,
> and use the RouteBuilder in a CamelContext.
> After all this is deployed, stop the bundle implementing the service. A
> ServiceUnavailableException should be thrown after a timeout, but the object
> that was injected into the RouteBuilder process the request - so the
> Blueprint Proxy is not used.
