title: Camel onException() not triggered
body: <p>I'm trying to test my onException code, but it isn't triggered under unit test. I can doCatch() the exception in the route, but otherwise it's just passed back to the unit test code.
  I've boiled it down to little more than a hardcoded throwException() and log() statement, but no luck. Using Camel 2.17.1.</p>
  
  <p>any ideas?</p>
  
  <p>route:</p>
  
  <pre><code>@Component
  public class BookingSummaryRouteBuilder extends RouteBuilder {
  [...]
  @Override
  public void configure() throws Exception {
  
      errorHandler(killSwitchErrorHandlerBuilder);
  
      onException(Exception.class)
              .description("We can get here functional exception and we mustn't send any mail in this case.")
              .log(LoggingLevel.INFO, "blahblah")
              .handled(true)
              /*.filter().method(exceptionAnalyserService, "isFunctionalException(${exception})")
                  .to(DIRECT_FUNCTIONAL_EXCEPTION)
                  .stop()
              //not functional exception*/
              .to("direct:dlq.fatal-error")
      ;
  
      from("activemq:queue:routemod.spot-booking.summary?concurrentConsumers=1")
              .routeId(BOOKING_SUMMARY_ENTRY_ROUTE)
              .description("Requests and receives a booking summary report")
              .log(LoggingLevel.INFO, "blah")
              .throwException(new ConfigurationException("something"))
