> The Javadoc
> ([https://static.javadoc.io/org.apache.camel/camel-core/2.23.3/org/apache/camel/StartupListener.html])
> for StartupListener is misleading (italics for emphasis):
> {quote}This can be used to perform any custom work when the entire
> [{{CamelContext}}|https://static.javadoc.io/org.apache.camel/camel-core/2.23.3/org/apache/camel/CamelContext.html]
> has been initialized and *almost* started. _For example this ensures that
> all Camel routes have been started and are up and running, before this
> callback is invoked._
> {quote}
> However, routes are not started within the callback. The following code, for
> example,
> {code:java}
> DefaultCamelContext context = new DefaultCamelContext();
> context.addStartupListener((c, alreadyStarted) -> {
> c.createProducerTemplate().sendBody("direct:doesNotExistYet", new
> Object());
> });
> context.addRoutes(new RouteBuilder() {
> @Override
> public void configure() {
> from("direct:doesNotExistYet").bean((Consumer<Object>)
> System.out::println);
> }
> });
> context.start();{code}
> fails with
> {code}
> Caused by:
> org.apache.camel.component.direct.DirectConsumerNotAvailableException: No
> consumers available on endpoint: direct://doesNotExistYet.

> I am aware that using ExtendedStartupListener or an EventNotifier makes this
> work, but it would be great if the Javadoc was updated (assuming this is
> intended behavior, I am not sure).
