> issue is that if I execute DefaultCamelContext().start(),
> the tomcat shutdown process will hang.
> Here's my spring config.  I have the following for 'inbound' return queues.
>   <bean id="returnQueues" class="com.ReturnedQueueRouteBuilder"
> lazy-init="false" init-method="init" destroy-method="stop">
>       <property name="routes">
>           <map>
>               <entry key="${a.returnQueue.name}">
>                   <bean class="com.ReturnedAProcessor">
>                       <property name="x" ref="y" />
>                   </bean>
>               </entry>
>               <entry key="${b.returnQueue.name}">
>                   <bean class="com.ReturnedBProcessor">

> ReturnQueueRouteBuilder looks like:

>    ...
>   public void init() {
>       camelContext.addComponent(activeMQName.trim(),
> ActiveMQComponent.activeMQComponent(remoteAddress.trim()));
>       try {
>           camelContext.addRoutes(this);
>           camelContext.start();
>       } catch (Exception e) {
>           log.error(e);
>       }
>   }
>     public void stop() {
>         try {
>             camelContext.stop();
>         } catch (Exception e) {
>             log.error(e);
>         }
>     }
>     @Override
>     public void configure() throws Exception {
>         for (Map.Entry<String, Processor> route : routes.entrySet()) {
>             from(route.getKey()).process(route.getValue());
>         }
>     }
>  I also see the following stack trace on tomcat shutdown, but I do not think this is directly the cause.
