jdbc-outbound-gateway async error handling in Spring - spring

Question

I'm trying to implement a fire-and-forget flow to log messages on a database by calling an Oracle procedure, everything works fine but I'd like to log any exception I get when, by any chance, I misconfigured the xml or whatever else could go wrong (any exception thrown by the procedure?).
I've searched for quite some time but I'm probably missing out something...
Here's the actual setting:
I've got a gateway interface
public interface gatewayInterfaceDEF{
void monitoring(Object payload);
}
XML definition of the gateway
<int:gateway service-interface="gatewayInterfaceDEF">
<int:method name="monitoring" request-channel="monitoringGatewayInbound" />
</int:gateway>
Then the JDBC-outbound-gateway xml configuration that calls an oracle procedure:
<int:channel id="monitoringGatewayInbound">
<int:dispatcher task-executor="monitoringTaskExecutor"/>
</int:channel>
<int-jdbc:stored-proc-outbound-gateway
id="monitoringGatewayProcedure" request-channel="monitoringGatewayInbound"
data-source="dataSource" stored-procedure-name="procedureName"
return-value-required="false" ignore-column-meta-data="true">
<int-jdbc:sql-parameter-definition
someparameters />
<int-jdbc:parameter parameter mapping />
</int-jdbc:stored-proc-outbound-gateway>
Thanks in advance
I've found this: http://java.dzone.com/articles/spring-async-and-exception
But it's not working: could it be me not being able to implement it, but still.
UPDATE: the wrapped log I get.

Since you are using ExcutorChannel, any Exception from the downstream flow is wrapped to the ErrorMessage and sent to the default errorChannel: http://docs.spring.io/spring-integration/docs/latest-ga/reference/html/configuration.html#namespace-errorhandler
By default all those exceptions are looged by LoggingHandler under category org.springframework.integration.handler with ERROR level.
From other side you can add ExpressionEvaluatingRequestHandlerAdvice to the <int-jdbc:stored-proc-outbound-gateway>: http://docs.spring.io/spring-integration/docs/latest-ga/reference/html/messaging-endpoints-chapter.html#expression-advice
And get deal with exception just only on that target MessageHandler
