java.net.http HttpClient 进入循环 wrapBuffer 返回 Status = OK HandshakeStatus = NEED_WRAP

Question

我无法将它发布到 JDK 错误报告中，因为我无法在我的公司基础设施设置之外重现它，但也许有人遇到过类似的事情。

Java版本： 11.0.6

构建HttpClient的代码：

return HttpClient.newBuilder()
        .version(HttpClient.Version.HTTP_1_1)
        .connectTimeout(Duration.ofSeconds(30))
        .proxy(ProxySelector.of(new InetSocketAddress(host, port)))
        .build();

我的请求如下所示：

HttpRequest request = HttpRequest.newBuilder()
        .uri(URI.create(URL))
        .timeout(Duration.ofSeconds(10))
        .GET()
        .header("Content-Type", "application/json")
        .header("x-auth-identifier", "<credential_username>")
        .header("x-auth-key", "<credentials_password>")
        .header("Accept", "application/json")
        .build();

使用： -Djdk.internal.httpclient.debug=true

有趣的是，第一次获取数据是成功的，然后进入循环并永远旋转（？）。 日志的后半部分是一切发生的地方。

有没有人遇到过这个？ 我知道它的Java HttpClient有问题，因为当我将实现交换为 RestTemplate 之类的东西（内部使用 Apache HttpClient）时，它工作正常。

这很可能是已在 JDK 12 中修复的 JDK-8214418。它也已向后移植到 Oracle JDK 11.0.4。 该问题不是直接可见的，但您应该在此处的公共评论线程中找到所有信息： http://mail.openjdk.java.net/pipermail/security-dev/2019-January/019142.html
