Description

When sending an In-Out message from a Bean SU to another component (here a Script SU) asynchronously then the response is not routed back to the calling SU even though it returns back to the correct BC. What is happening is that the Consumer Endpoint of the called SU is used. In the attached test the called SU is based on a Script BC and so it cannot even find a service.

Note: the problem is not somewhat shortcut by the issues ~~SM-994~~ (https://issues.apache.org/activemq/browse/SM-944). I hacked the issue and I see that the called SU is called.

The attached file is a ZIP file of a complete project. To run the test build the project with "mvn install".

The InOutReceiver Script component is setting a response (Out Message) and sending the message back through the delivery channel. The message is then picked up correctly by a BeanEndpoint but because of the wrong address (service) it ends up in the Consumer Endpoint of the wrong Bean. The exception (Unkown consumer exchange) is another problem that comes from the fact that the list of requests are a private member of an Endpoint and the Consumer and the Provider are two different Endpoint instances. I fixed that issue but it does not make any difference.
