recipientlistrouter not working with 1.0.3 update

[jebscar]

a config that was working without issue now seems to have an issue when updating to 1.0.3. I am assuming there is something I need to update in my config, but the errors almost sound like an issue in the framework. any thoughts?

This is happening because the RecipientListRouter no longer extends AbstractMessageRouter, and this is the check in the RouterFactoryBean:

  private AbstractMessageRouter createRouter(Object targetObject, String targetMethodName) {
      if (targetObject instanceof AbstractMessageRouter) {
          ...
          return (AbstractMessageRouter) targetObject;
      }
      MethodInvokingRouter router = ...

So, it's trying to create a MethodInvokingRouter instance.

The reason that RecipientListRouter no longer extends AbstractMessageRouter is that it needed to be more flexible to support the 'apply-sequence' attribute:
http://jira.springframework.org/browse/INT-679

Unfortunately this caused a regression issue because of that code above.

Can you please open a JIRA issue for this?

In the meantime, you should be able to use the new 'recipient-list-router' element directly within the 'chain':
http://jira.springframework.org/browse/INT-697

Can you please try that?
