Review Comment:
I add the similar changes to `multicast` and `recipientList` processors.
Aslo an unit test has been added to test with a pooling data source. For
`enrich`, the default aggreate stragtegy is using the new exchange, so it works
with transacted. But if the custom aggregate stragtegy is used, the users have
to copy `JpaConstants.ENTITY_MANAGE` propery from the newExchange by
themseleves. I also provide `JpaHelper.copyEntityManagers` method to do this
copying.
