Adding this example that may be useful to others without digging all the examples in the link.

Define a bean/processor that will launch a separate thread. This new thread will call stop() on the active CamelContext.

public class ShutdownBean {

    private final static Logger log = LoggerFactory.getLogger(ShutdownBean.class);

    public void process(Exchange exchange) throws Exception {
        final CamelContext camelContext = exchange.getContext();

        Thread shutdownThread = new Thread(() -> {
            Thread.currentThread().setName("ShutdownThread");
            try {
                camelContext.stop();
            } catch (Exception e) {
                log.error("Errore during shutdown", e);
            }
        });

        shutdownThread.start();
    }
}

In your application context define this route and call it when you need to shutdown Camel.

Note: enableHangupSupport() is deprecated on newer Camel versions: is enabled by default now, so no longer need to call this method.
