How to know my spring bean is discarded in thread pool or memory ?

[차정호]

Hello.

I love Camel and am using it for my product. 

I set my bean in the spring custom thread(prototype) scope, 
And I configure the camel route the below

<beans>
...
        <bean id="myBean" class="com.brm.test.MyBean"
            scope="thread" init-method="start" destroy-method="stop">

        <camelContext id="camel"
xmlns="http://camel.apache.org/schema/spring";>
        ...
                <route>
                        <from uri="seda:test" />
                                <threads poolSize="10" maxPoolSize="20">
                                        <setExchangePattern
pattern="InOnly" />
                                        <to
uri="bean:myBean?method=process" />
                                </threads>
                </route>
        ...
        </camelContext>
...
</beans>

When I send message to seda:test,
In myBean the init-method start() was called ok. 
But I have not seen the destroy-method stop() at all in the spring
thread(prototype) scope. 

My bean maintains some resources in its life cycle as the thread scope or
the prototype scope. 

But I don't know how to clear the resources of myBean when the thread using
myBean is discared or bean is destoryed. 

If spring destroy-method is not applicable, Is Some camel listener possible
? 

Could someone help me? 

Thanks a lot before.
