在Java 11上的SocketTimeout，但在Java 8上没有。

问题描述 投票：4回答：1

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

我使用 MSGraph API (1.7.0) 对 Onedrive API 进行了多次调用。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）。

当我用 Java 8 执行程序时，我没有收到异常。当我用java 11执行程序时，大约60%的调用都会出现Socket超时异常。

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

有人遇到过这样的情况吗？

[UPDATE-1]

这些是我测试过的环境。

  • Oracle的JDK 1.8.0_192 --> 完美。在大约400次调用中没有出现任何错误
  • Openjdk 11.0.7和Oracle的jdk 11.0.3--&gt；大量的Sokcet超时异常。

在此，你有堆栈跟踪。

将okhttp依赖关系覆盖到3.14.9和4.7.2版本（最新版本）后，虽然有一些变化，但一切还是一样。除了常见的超时异常。

在JDK9（或JDK8 252+）上的OkHttp，默认会协商HTTP2。 很有可能与这个变化有关。

试着构建一个没有HTTP2的客户端，看看你是否还能得到这个问题。

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

如果能解决这个问题，很可能是服务器与HTTP2不兼容，或者是与连接重用有关，比如一个连接上有太多的请求。

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

微软Graph 1.7.1有一个依赖关系。 的 Microsoft Graph Core 1.0.0，它依赖于 OKHttp版本3.12.1.

根据 Square的OKHttp变更日志，3.12.x是Java 7以上的LTS版本。. 这意味着它将期望某些包modules和类名存在，而在Java 9及以上版本后可能就不存在了(下文更多)。

3.14.8版本引入了一些对Java 9 API变化的修复，这些变化破坏了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。

旁白一下，这是在从Java 8移植到Java 9及以上版本时常见的问题。拼图项目 将臃肿的JDK的许多组件分解成模块。许多使JDK变得如此庞大的 "企业 "特性被分离成了自己的模块，你必须指定将其包含在你的项目中。许多Java 8及以前的库希望这些模块仍然是 "开箱即用 "的，这就导致了奇怪的故障，比如你现在看到的--但更常见的是臭名昭著的 NoClassDefFoundError.
