Issue

There is a SwitchYard service like this:

[camel DSL component] -- [JPA Reference Binding]

In the Camel component, onException() is coded like this

public void configure() {

 onException(Throwable.class).log(LoggingLevel.INFO, "***** catch Exception in the camel route *****");

 from("switchyard://PeriodicService").log(
  "Received message for 'PeriodicService' : ${body}").to("switchyard://StoreService").log("done");
    }

Interface for the JPA Reference Binding is like this

void storeGreeting(Greet event);

Although Exception relating with SQL occurs in JPA Reference Binding, onException() is never invoked.
