Произошла ошибка во время запуска верблюда из-за круговой зависимости

Question

Произошла ошибка во время запуска верблюда из-за круговой зависимости

При размещении комплекта (используя camel) На Карафе я вижу следующее исключение. Приведенное ниже исключение возникает только при запуске пакета. После этого все работает нормально. Исключение, похоже, не влияет на нашу функциональность. Вопрос идет обоим camel 2.16.1 (развернуто на servicemix 6.1.0) а также camel 2.16.3 (развернуто на servicemix 7.0.0M2).

мой blueprint разделен на три файла. Их упрощенная версия показана ниже:

blueprint.xml размещен здесь
productBeans.xml размещен здесь
camelContext.xml размещен здесь

Может кто-нибудь, пожалуйста, дайте мне знать, почему это исключение появляется при запуске пакета? Из приведенной ниже трассировки стека видно, что это происходит из-за некоторой циклической зависимости. Как я могу обойти это?

РЕДАКТИРОВАТЬ - Кажется, ошибка в том, что jsonRPCProcessor использует myTemplate как показано ниже:-

<bean id="jsonRPCProcessor"     class="com.j1.orchestratorservice.basecomponent.processor.JSONRPCProcessor">
        <argument ref="myTemplate" />
        <argument>
            <map>           
                <!-- Product End Points -->
                <entry key="Product.createProducts" value-ref="createProductsWFInfo" />             
            </map>
        </argument>
        <argument ref="exceptionHandler" />
    </bean>

в то время как myTemplate определяется в camelContext который в свою очередь использует jsonRPCProcessor как показано ниже:-

<camelContext xmlns="http://camel.apache.org/schema/blueprint"
        useMDCLogging="true">
        <template id="myTemplate" />
        <route id="orchestrator-service-route">
            <from uri="jetty:http://0.0.0.0:8888/orchestratorservice" />
            <process ref="jsonRPCProcessor" />
        </route>
        <route id="file-upload-service-route">
            <from
                uri="jetty:http://0.0.0.0:8889/fileuploadservice?enableMultipartFilter=true" />
            <process ref="fileUploadProcessor" />
        </route>
...
</camelContext>

Я пытался установить producer в моем собственном процессоре, как указано в этой ссылке. Может кто-нибудь предложить мне другой способ установки producer по моему обычаю jsonRPCProcessor чтобы это не привело к какой-либо круговой зависимости?

Я могу обойти это, удалив myTemplate от jsonRPCProcesor а также fileUploadProcessor, Теперь мой jsonRPCProcessor выглядеть примерно так:

<bean id="jsonRPCProcessor" class="com.j1.orchestratorservice.basecomponent.processor.JSONRPCProcessor">
    <argument>
        <map>           
            <entry key="Product.createProducts" value-ref="createProductsWFInfo" />
        </map>
    </argument>
    <argument ref="exceptionHandler" />
</bean>

Аннотированный ProducerTemplate(в базовом классе) в моем коде с @EndPointInject, Примерно так:-

@EndpointInject
protected ProducerTemplate myTemplate;
