   如下泛化调用代码，JVM内存会不断升高，不会释放，有什么建议吗？
   `
    ApplicationConfig applicationConfig = new ApplicationConfig();
           applicationConfig.setName(applicationName);
   
           RegistryConfig registry = new RegistryConfig();
           registry.setAddress(registryAddress);
           registry.setGroup(registryGroup);
           registry.setRegister(false);
           registry.setEnableEmptyProtection(false);
   
           ReferenceConfig<GenericService> reference = new ReferenceConfig<>();
           reference.setInterface(interfaceName);
           reference.setGeneric("true");
           reference.setFilter(filters);
           reference.setRetries(0);
           reference.setRegistry(registry);
   
           GenericService srv = reference.get();
           Preconditions.checkState(srv != null, "找不到服务:" + interfaceName);
   `
   从内存快照种可以看到非常多(几百万级别)HashMap，char[]，如：
