Channel interceptor without subscribers

[m.ugues]

Hi all.
I need to configure a channel with a interceptor without a subscriber, something like this below:

<int:channel id="endPointEventMessageChannel">
<int:interceptors>
<ref bean="onlineMdcCleanerInterceptor"/>
</int:interceptors>
</int:channel>

If I run the application I receive this exception:
Caused by: java.lang.IllegalStateException: Dispatcher has no subscribers.

The reference manual shows the same example:
<channel id="exampleChannel">
<interceptors>
<ref bean="trafficMonitoringInterceptor"/>
</interceptors>
</channel>

Is not possible to have a channel only with an interceptor without a subscriber?

Kind regards
Massimo

Could you please describe your use case? What are you trying to accomplish?
Your current configuration is obviously wrong since you are defining a DirectChannel which is there to support P2P messaging model and P2P model states that both producer and consumer *must* be present.

So please describe your use case and we'll help you to find the right solution.
