> There is no JMX MBean for onException component, which makes statistics unavailable.
> For example:
> {noformat}
> import javax.jms.ConnectionFactory;
> import org.apache.camel.CamelContext;
> import org.apache.camel.Exchange;
> import org.apache.camel.Processor;
> import org.apache.camel.builder.RouteBuilder;
> import org.apache.camel.impl.DefaultCamelContext;
> /**
>  * A Camel Router
>  */
> public class OnExceptionRouteBuilder extends RouteBuilder {
> 	/**
> 	 * A main() so we can easily run these routing rules in our IDE
> 	 */
> 	public static void main(String... args) throws Exception {
> 		CamelContext camelContext = new DefaultCamelContext();
> 		ConnectionFactory jmsConnectionFactory = new org.apache.activemq.ActiveMQConnectionFactory(
> 				"tcp://localhost:61616");
> 		camelContext.addComponent("jms",
> 				org.apache.camel.component.jms.JmsComponent
> 						.jmsComponent(jmsConnectionFactory));
> 		camelContext.addRoutes(new OnExceptionRouteBuilder());
> 		camelContext.start();
> 		Thread.sleep(100000000);
> 	}
> 	/**
> 	 * Lets configure the Camel routing rules using Java code...
> 	 */
> 	public void configure() {
> 		onException(javax.jms.JMSException.class).process(new Processor() {
> 			@Override
> 			public void process(Exchange exchange) throws Exception {
> 				System.out.println("error");
> 			}
> 		}).to("log:exception");
> 		from("timer://myTimer?period=2000&repeatCount=1").setBody()
> 				.simple("hello JMS!").process(new Processor() {
> 					@Override
> 					public void process(Exchange exchange) throws Exception {
> 						System.out.println("We will write to ActiveMQ queue: "
> 								+ exchange.getIn().getBody(String.class));
> 					}
> 				}).to("jms:queue:hello");
> 	}
> }
> {noformat}
> And there are only two processors(We have four in the test case) in org.apache.camel/processors,
none for onException branch. See the picture attached.
