www-authenticate请求头导致JettyClientHttpConnector调用阻塞异常

环境 #

• Spring Boot 3.3.4
• Spring Web 6.1.1

原正常运行环境 #

• Spring Boot 2.7.18
• Spring Web 5.3.31

问题背景 #

从Spring Boot 2.7.18迁移到3.3.4后，使用配置了JettyClientHttpConnector的WebClient调用返回WWW-Authenticate响应头的接口时，出现无限阻塞，无法正常获取响应。该场景在Spring Boot 2中可正常运行，已尝试最基础的连接器配置，只要接口返回该响应头就触发异常。

示例代码 #

仅配置WebClient使用JettyClientHttpConnector测试，代码如下：

WebClient client =
        WebClient.builder()
            .baseUrl("your-url-with-www-authenticate-header-in-response")
            .clientConnector(new JettyClientHttpConnector())
            .build();

异常信息 #

调用接口后阻塞，超时后抛出如下错误：

完全相同的代码在Spring Boot 2环境中可正常处理请求，求解决该问题。
