>             Project: Apache Camel
>          Issue Type: Bug
>          Components: camel-spring

> Because CamelBeanPostProcessor.setCamelContext(SpringCamelContext) takes the class SpringCamelContext
as its parameter, bean initialization fails if SpringCamelContext is proxied.  The error is
as follows:
> {code}
> org.springframework.beans.factory.BeanCreationException: Error creating bean with name
'camelContext:beanPostProcessor': Initialization of bean failed; nested exception is org.springframework.beans.TypeMismatchException:
Failed to convert property value of type [$Proxy61] to required type [org.apache.camel.spring.SpringCamelContext]
for property 'camelContext'; nested exception is java.lang.IllegalArgumentException: Cannot
convert value of type [$Proxy61] to required type [org.apache.camel.spring.SpringCamelContext]
for property 'camelContext': no matching editors or conversion strategy found
> {code}
> In my project's Spring conf, we declare <aop:aspectj-autoproxy/>, which causes
all Spring beans to be proxied.  This triggers the problem shown above.  The problem should
be reproducible by adding <aop:aspectj-autoproxy/> to any Spring config that uses <camel:camelContext>.
> The fix will be to separate the interface and class for SpringCamelContext, and use the
interface where appropriate.
