Apache Camel配置无效代理仍可请求成功问题排查

我是Apache Camel新手，通过编码学习。编写了如下简单路由：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
        http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd ">

    <camelContext id="camelContext" xmlns="http://camel.apache.org/schema/spring">
        <route>
            <from uri="timer:timer?repeatCount=1"/>
            <to uri="https://v2.jokeapi.dev/joke/Any"/>
            <log message="${body}"/>
        </route>
    </camelContext>

</beans>

对应的集成测试代码为：

@CamelSpringBootTest
public class JokeIT {

    @Autowired
    CamelContext camelContext;

    @Test
    void  test_positive() throws InterruptedException {
        NotifyBuilder notification = new NotifyBuilder(camelContext)
                .from("timer:timer?repeatCount=1").whenDone(1)
                .create();
        camelContext.start();
        notification.matches(10, TimeUnit.SECONDS) ;
        camelContext.stop();
    }

}

执行命令mvn clean compile test-compile failsafe:integration-test后，测试通过并正常打印响应结果。但奇怪的是，即使将to节点的URI修改为<to uri="https://v2.jokeapi.dev/joke/Any?proxyAuthHost=abcd"/>，或是设置不存在的proxyHost参数，测试仍能通过并打印响应内容。我预期配置不可用代理时测试应该失败，请问这是什么原因？是否我遗漏了某些配置？
