Context

vert.x 4.4.9 and above, http server will not receive requests after deployment

Steps to reproduce

@slf4j
public class HttpDeviceNetwork implements IDeviceNetwork {

private Vertx vertx;

private HttpServer backendServer;

private HttpConfig httpConfig;

private CountDownLatch countDownLatch;

@Override
public void send(String topic, int qos, byte[] content) {

}

@Override
public NetworkType getType() {
    return NetworkType.http;
}

@Override
public void init(NetworkConfig config) {
    try {
        vertx = Vertx.vertx();
        httpConfig = config.getConfig("http", HttpConfig.class);
        backendServer = vertx.createHttpServer();
        log.info("======>>>>>http network init success.");
    } catch (Exception e) {
        log.error("======>>>>>http network init fail.");
    }
}

@Override
public void start() {
    Router router = Router.router(vertx);
    router.route().handler(BodyHandler.create());

    router.get("/test").handler(rc -> {
        log.info("======>>>>>http network request received.");
        HttpServerResponse httpServerResponse = rc.response();
        httpServerResponse.putHeader("content-type", "text/plain");
        httpServerResponse.end("Hello from Thingverse HTTP Server!");
    });

    backendServer.requestHandler(router)
            .listen(httpConfig.getPort(), http -> {
                if (http.succeeded()) {
                    log.info("http server create succeed,port:{}", httpConfig.getPort());
                } else {
                    log.error("http server create failed", http.cause());
                }
            });
}

@Override
public void stop() {
    backendServer.close();
}

}

Deploy a server instance that starts up with no errors, but just doesn't receive requests.A version 4.4.8 or lower is fine

Extra

• Anything that can be relevant such as OS version, JVM version
• springboot 3.2.6
• jdk21

The release notes are short and I can't see anything other than a Netty upgrade that could be related.

Given Vert.x is embedded into a Spring app in your case, perhaps there's a dependency conflict somewhere?

[xddcode]

The same code would work fine in version 4.4.8, but would not work at startup if you switched to 4.5.x

Please share a minimal reproducer on GitHub. This snippet alone works for me with any version.
