    Resolver newResolver = e -> null;
    CountDownLatch configUpdated = new CountDownLatch(1);
    CountDownLatch configVerified = new CountDownLatch(1);
    Thread updaterThread = new Thread() {

        @Override
        public void run() {
            router.reconfigure(config -> {
                config.setResolver(newResolver);
                // Signal that config has been updated
                configUpdated.countDown();
                // configuration is not yet in effect
                try {
                    configVerified.await();
                } catch (InterruptedException e) {
                    throw new RuntimeException(e);
                }
            });
        }
    };
    updaterThread.start();
    // Wait until updater thread has updated the config
    configUpdated.await();
    Assert.assertNotSame("Update should not yet be visible", newResolver, router.getConfiguration().getResolver());
    // Allow the update thread to exit the configure method
    configVerified.countDown();
    // Wait for updater thread to finish
    updaterThread.join();
    Assert.assertSame("Update should now be visible", newResolver, router.getConfiguration().getResolver());
}
