Java 11 上的 SocketTimeout，但 Java 8 上没有答案

【问题标题】：SocketTimeout on Java 11 but not on Java 8Java 11 上的 SocketTimeout，但 Java 8 上没有
【发布时间】：2020-05-26 20:58:06
【问题描述】：

当我的 Java 程序使用 Java 8 和 Java 11 运行时，我有一个非常奇怪的行为差异。

我正在使用 MSGraph API (1.7.0) 对 Onedrive API 进行多次调用。为了进行这些调用，我使用 4 个并行线程来同步硬盘上的大量文件（大约 1000 个）。

当我使用 Java 8 执行程序时，我没有遇到任何异常。当我使用 java 11 执行它时，在大约 60% 的调用中会出现 Socket Timeout Exception。

要配置IGraphServiceClient，我使用的是默认配置。就我而言，在这种情况下，HTTP Provider 是 OKHttp3。

有没有人经历过这样的事情？

[UPDATE-1]

这些是我测试过的环境：

Oracle 的 JDK 1.8.0_192 --> 完美。大约 400 次调用中没有错误
Openjdk 11.0.7 和 Oracle 的 jdk 11.0.3 --> 大量 Sokcet 超时异常

这里你有堆栈跟踪：

【问题讨论】：

如果使用 Java 8 在 Eclipse 之外运行代码会发生什么？
Java 8 到 Java 11 是一个很大的变化。许多标准库被分解成必须导入的单独包。超时可能掩盖了缺少库中的其他一些错误。粘贴您的堆栈跟踪，以便我们提供帮助。
@AlexR，它运行良好。确实我更新了标题。问题不再是环境（Eclipse 或 CLI），而是我用来运行程序的 Java 版本
看起来罪魁祸首是 OkHttp：MSGraph 使用的任何版本的 OkHttp3 MSGraph 似乎都存在与 Java 11 的兼容性问题。有趣的是，OpenJdk 11 和 Oracle Jdk 11 都表现出相同的行为。问：是否有机会在代码中更改 OkHttp3 超时？比如设置为“0”？
您是否使用 Maven 来解决依赖关系之类的问题？看起来 MSGraph 依赖于 Graph Core 1.0.0，它依赖于 OKHttp 3.12.1。您可以尝试通过在 POM 中手动指定它来覆盖 OKHttp 3.12.1 导入并选择更新的版本。看看这是否有帮助... 根据 Square 在 OKHttp 上的页面，3.12.x 是 Java 7+ 的 LTS，这意味着它取决于 Java 9 及更高版本中外化的功能。他们甚至在 3.14.8 中有一个错误修复，可以防止 Java 8u252+ 崩溃，处理从 Java9 向后移植的 API 更改

标签： java java-8 okhttp java-11

【解决方案1】：

JDK9（或 JDK8 252+）上的 OkHttp，默认会协商 HTTP/2。很有可能与这种变化有关。

尝试在没有 HTTP/2 的情况下构建客户端，看看是否仍然遇到此问题。

  val client = OkHttpClient.Builder()
      .protocols(listOf(Protocol.HTTP_1_1))
      .build()

如果它修复了问题，则可能是服务器与 HTTP/2 不兼容，或者与连接重用有关，例如单个连接上的请求过多。

kekolab 20201030 更新。

Microsoft 通过将协议版本限制为 1.1 来解决此问题，这与上面的 OP Yuri 所建议的完全一样。好东西，代码中引用了这个线程：https://github.com/microsoftgraph/msgraph-sdk-java/pull/473/files#

【讨论】：

mmm... 试试看... 其实OKHttp Client的创建是埋在SDK里面的，所以需要一些时间（如果我决定这样做的话，实际上......这是一个个人项目。我可以决定我懒得让它在 Java 8 上运行 :D)
成功了！我在创建客户端的地方设置了一个刹车点，并更改了删除 HTTP2 的协议列表。现在的问题是如何在隐藏的 Microsoft SDK 中覆盖它。
向 Microsoft（不是我的）提交的关于图形 API 的所有异常的错误文件：github.com/microsoftgraph/msgraph-sdk-java/issues/313 在 cmets 中，我的第一个回复 (github.com/microsoftgraph/msgraph-sdk-java/issues/…) 我报告了 @yuri-schimke 的分析和第二篇文章我解释了使用替代客户端（Apache Commons HttpClient）的困难，以及我如何通过仅使用 HTTP1/1 的 OKHttpClient（尽管有反射）来规避这个问题：github.com/microsoftgraph/msgraph-sdk-java/issues/…
已提交建议的解决方案github.com/microsoftgraph/msgraph-sdk-java/commit/… - 升级后 - 我们仍然继续收到“SocketException: socket closed”错误。有什么线索吗？ @kekolab
希望在下一次 OkHttp 之后这可以恢复 - 跟踪 SDK 中的错误 github.com/microsoftgraph/msgraph-sdk-java-core/issues/88

【解决方案2】：

您使用的OKHttp版本与Java 11（实际上是Java 9及以上）不兼容。

Microsoft Graph Core 1.0.0 的Microsoft Graph 1.7.1 has a dependency，它依赖于OKHttp version 3.12.1。

根据Square's changelog for OKHttp, 3.12.x is a LTS version for Java 7+。这意味着它会期望某些包/模块和类名存在，这可能在 Java 9 及更高版本之后不存在（更多内容见下文）。

Version 3.14.8 introduced some fixes for Java 9 API changes that break OKHttp.

你应该在你的 POM 中手动指定这个版本的 OKHttp，或者包含这个 Jar 来覆盖旧版本的隐式依赖。

顺便说一句，这是从 Java 8 移植到 Java 9 及更高版本时的常见问题。 Project Jigsaw 将臃肿的 JDK 的许多组件分解为模块。使 JDK 如此庞大的许多“企业”功能都被分离到它们自己的模块中，您必须指定将其包含在您的项目中。许多 Java 8 天或更早版本的库都希望这些模块仍然“开箱即用”存在，这会导致像您所看到的那样奇怪的失败 - 但更常见的是臭名昭著的 NoClassDefFoundError。

【讨论】：

OkHttp 版本强烈向后兼容。您不需要固定到旧版本，如果这样做有帮助，请打开一个错误！
@JesseWilson OP 可以使用任何更新版本的 OKHttp，只要它符合他们对 Microsoft Graph 的原始要求。我指出默认版本不仅仅是过时的，考虑到明确的错误修复行项目，它可能会在 Java 11 上出现问题。
是的，我正在使用依赖管理工具（实际上是 Gradle）。今晚我会试一试（我希望今晚有时间），并让你知道在覆盖隐式 MSGraph 依赖项后一切是否仍然有效（并且最终会更好）。
@SnakeDoc，可惜我们并不幸运（请参阅原始问题中的 UPDATE-2）。我想我会向 Microsoft 和 OKhttp 提交两份错误报告，我想
