/**
* Verify that no inbound messages are lost when exceptions occur. 
* The message must either make it all the way to the SEDA queue (in the case of
* an asynchronous inbound endpoint), or be restored/rolled back at the source.
*
* In the case of JDBC, this will cause the ACK query to not be executed and therefore
* the source data will still be present the next time the database is polled.
