Tomcat NioEndpoint - 运行套接字处理器时出错

Question

在 Spring Boot 生产应用中，偶尔会抛出以下异常：

o.a.t.u.n.NioEndpoint : Error running socket processor

很难说是什么导致了异常，因为在同一线程之前或之后没有日志。查看堆栈跟踪，它可能发生在到达任何自定义请求预处理代码之前，在 SSL 握手期间，这可能是之前没有日志的原因。（生产应用程序当前正在登录级别 TRACE。）

可能是什么原因以及如何解决？

Spring Boot 版本：2.2.5.RELEASE

编辑：

我最近遇到了一个非常相似的案例，但是stacktrace却大不相同：

Answer 1

这似乎是由 JRE 问题引起的：

http://hg.openjdk.java.net/jdk/jdk/rev/01d8eae542ff

https://bugs.openjdk.java.net/browse/JDK-8218889

它被修复了

• 11.0.8b01
• 11.0.7b04
• 8u261 b05

您使用的是受影响的 JRE 版本吗？

至于你提到的第二个问题：

https://bugs.openjdk.java.net/browse/JDK-8241248

这是一个选项问题（但提到了解决方法）。

请研究这两个问题，尝试更新以解决第一个问题，并查看在第二个问题没有可用修复程序的情况下是否可以应用解决方法。
