The code blocking in ExtendeLoader.getExtendeClasses, and the relevant source code is partially pasted

public static Map<ClassLoader, Set<URL>> loadResources(String fileName, Collection<ClassLoader> classLoaders)
            throws InterruptedException {
        Map<ClassLoader, Set<URL>> resources = new ConcurrentHashMap<>();
        CountDownLatch countDownLatch = new CountDownLatch(classLoaders.size());
        for (ClassLoader classLoader : classLoaders) {
            GlobalResourcesRepository.getGlobalExecutorService().submit(() -> {
                resources.put(classLoader, loadResources(fileName, classLoader));
                countDownLatch.countDown();
            });
        }
        countDownLatch.await();
        return Collections.unmodifiableMap(new LinkedHashMap<>(resources));
    }

my docker start command：

docker run --name=test --cpus=2 -m 4g --memory-swap=4g -d -p 22222:22222 --env='JAVA_OPTS=-XX:+UseG1GC -XX:+UseContainerSupport -XX:InitialRAMPercentage=50.0 -XX:MinRAMPercentage=70.0 -XX:MaxRAMPercentage=70.0 -XX:-UseAdaptiveSizePolicy -XX:+UnlockExperimentalVMOptions -XX:+UseWisp2' --env='SPRING_PROFILES_ACTIVE=test' --env='CUSTOMIZE_OPTS=-Ddubbo.application.qos-port=22222 -Ddubbo.application.qos-enable=true -Ddubbo.application.qos-accept-foreign-ip=true -Ddubbo.application.qos-anonymous-access-permission-level=NONE' -d registry.cn-beijing.aliyuncs.com/test/xxx:tag

I don't have any troubleshooting ideas left 😭
