I want to catch all Exception from routes.

I add this OnExeption :

```
onException(Exception.class).process(new MyFunctionFailureHandler()).stop();

```

Then, I create the class MyFunctionFailureHandler.

```
public class MyFunctionFailureHandler  implements Processor {

@Override
public void process(Exchange exchange) throws Exception {
    Throwable caused;

    caused = exchange.getProperty(Exchange.EXCEPTION_CAUGHT, Throwable.class);

    exchange.getContext().createProducerTemplate().send("mock:myerror", exchange);
   }

}

```

Unfortunately, it doesn't work and I don't know why.

if there is an Exception, the program must stop.

How can I know why this code doesn't work!!

Thanks.
