Request-reply outbound endpoint sends reply to caller temp queue instead of self temp queue

  None

When calling a request-reply jms:outbound-endpoint (let's call it queue B) inside a flow invoked from a request-reply jms:outbound-endpoint (let's call it queue A) from other flow, the reply is placed on the temp queue of the caller (queue A) instead of queue B.

The output is "WRONG VALUE" when it should be "CORRECT VALUE".
