Quinn Stevenson commented on CAMEL-9570:
----------------------------------------

I found a workaround - I haven't tested it throughly, but it works in the basic 
case of my test.

I extended the BlueprintCamelContext, and then used that context as a normal 
bean rather than using the camel blueprint extension namespace.

Here's the extended context I used

public class SimpleCamelBlueprintContext extends BlueprintCamelContext {
    public SimpleCamelBlueprintContext(BundleContext bundleContext, 
BlueprintContainer blueprintContainer) {
        super(bundleContext, blueprintContainer);
    }

    public void setRoute(RouteBuilder builder) throws Exception {
        this.addRoutes(builder);
    }

    @Override
    public void init() throws Exception {
        super.init();
        super.start();
    }

    @Override
    public void destroy() throws Exception {
        super.destroy();
    }
}

And here's a sample blueprint snippit

<bean id="bean-route" class="com.pronoia.camel.builder.BeanConsumerBuilder">
        <property name="timerName" value="$camel{timerName}" />
        <property name="timerPeriod" value="$camel{timerPeriod}" />
        <property name="trace" value="$camel{trace}" />
        <property name="cacheBean" value="$camel{cacheBean}" />
        <property name="beanInstance" ref="alternate-service" />
        <!--
        <property name="beanInstance" ref="alternate-service" />
        <property name="beanInstance" ref="osgi-service" />
        <property name="beanInstance" >
            <bean class="com.pronoia.osgi.service.MyServiceWrapper" >
                <property name="delegate" ref="osgi-service" />
            </bean>
        </property>
        -->
    </bean>

    <bean id="simple-camel-context" 
class="com.pronoia.camel.context.SimpleCamelBlueprintContext" 
init-method="init" destroy-method="destroy">
        <argument index="0" ref="blueprintBundleContext" />
        <argument index="1" ref="blueprintContainer" />
        <property name="route" ref="bean-route" />
    </bean>

So as near as I can tell, something in the camel blueprint namespace extension 
is causing the issue.

>             Project: Camel
>          Issue Type: Bug
>          Components: camel-blueprint, camel-core

>            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.
