This is how it works in Camel. The consumer kicks off the routing, when you
use the processor to process the Exchange, the consumer has created.
You can do this synchronously
try {
getProcessor().process(exchange);
} catch (Exception e) {
exchange.setException(e);
}
if (exchange.getException() != null) {
// some exception happened
}
Then in your Camel routes you should of course not use an error
handler that will handle the exception such
as the DeadLetterChannel etc.
