Quarkus 原生构建问题：通过 ServiceLoader 找不到 NameResolverProviders

Question

我有一个经过充分测试的 Quarkus 微服务，我正在尝试以本机模式构建它。我正在使用最新的 Quarkus 3.2.2.Final。 JVM 模式下不存在问题。

当我启动本机微服务时，在启动过程中我收到警告：

"io.grpc.NameResolverRegistry","level":"WARNING","message":"No NameResolverProviders found via ServiceLoader, including for DNS. This is probably due to a broken build. If using ProGuard, check your configuration"

当然，此后，与 etcd 的通信失败并显示

cannot find a NameResolver for ip:///localhost:2379

，并且应用程序退出。

在 JVM DEBUG 模式下，我可以看到总共注册了 7 个解析器。

我尝试显式注册反射类，但没有帮助。

@RegisterForReflection(targets={
    IPNameResolver.class,
    HttpNameResolver.class,
    HttpResolverProvider.class,
    IPResolverProvider.class,
    DnsSrvNameResolver.class,
    NameResolverProvider.class,
    LoadBalancerProvider.class,
    DnsNameResolverProvider.class,
    NameResolverRegistry.class
})

我怀疑这不是由于类未正确注册造成的，而是由动态类加载中一些与本机相关的特性引起的。

接下来要尝试什么有什么建议吗？我在构建过程中没有看到任何警告。

编辑：

Installed features: [cache, cdi, hibernate-validator, kafka-client, micrometer, mongodb-client, mongodb-panache, narayana-jta, quartz, reactive-routes, resteasy-reactive, resteasy-reactive-jackson, scheduler, security, security-properties-file, smallrye-context-propagation, smallrye-health, smallrye-jwt, smallrye-reactive-messaging, smallrye-reactive-messaging-kafka, vertx]

我还在本机构建器调用行中看到：

-H:-UseServiceLoaderFeature

。

编辑 2，堆栈跟踪：
