cxf运行时异常未知客户端异常

我正在使用一个简单的骡子流，它将一个spring bean作为一个组件，并使用石英端点定期执行它。我的cxf客户端和配置对我来说都很好，但由于某种原因，我在尝试发送请求时遇到异常。

我的课程如下：

@Component
@DependsOn("restfulClient")
public class Transmitter implements Callable{

    private static final Logger logger = 
    LoggerFactory.getLogger(Transmitter.class);

    @Autowired
    private RestfulClient restfulClient; 

    public Object onCall(MuleEventContext eventContext) throws Exception {
        logger.info("In Transmitter"); 
        try {
            String result = restfulClient.ping(); 
            logger.info("Result: {}" , result); 

        } catch (Exception e){
            logger.error("Exception in Transmitter" ,e); 
        }
        return null;
    }
}

我的客户：

@Produces({"text/plain"})
@Path("/subscription")
public interface RestfulClient {

    @GET
    @Path("/ping")
    public String ping(); 
}

在applicationContext.xml我定义了cxf bean并启用了cxf logging：

<jaxrs:client id="restfulClient"
                serviceClass="com.ws.RestfulClient"
                address="${prop.restful.url}">
    <jaxrs:features>
        <cxf:logging/>
    </jaxrs:features>
</jaxrs:client>

，url在application.properties文件中定义，在调试模式下，它成功构建了url。

当我在邮递员上尝试网址时，它工作正常，我得到OK作为结果，但它在代码中不起作用。

我得到的例外是：

我发现了问题。问题在于

<jaxrs:features>
    <cxf:logging/>
</jaxrs:features>

属于格式错误的架构......（老实说，我想知道为什么不会给这样的错误命名，而不是模糊的未知客户端异常！）
