Tomcat NioEndpoint - 运行套接字处理器时出错 [英] Tomcat NioEndpoint - Error running socket processor
问题描述
在 Spring Boot 生产应用中，偶尔会抛出以下异常:
In a Spring Boot production app, the following exception is occasionally thrown:
o.a.t.u.n.NioEndpoint : Error running socket processor
java.util.NoSuchElementException: No value present

很难判断是什么导致了异常，因为在同一线程之前或之后都没有日志.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.)
It is hard to tell what causes the exception, as there are no logs before or after by the same thread. Looking at the stack-trace, it might occur before any custom request pre-processing code is reached, during the SSL handshake, which might be the reason there are no logs before. (Production application is currently logging on level TRACE.)
可能是什么原因以及如何解决?
What could be the cause and how to fix it?

我最近遇到了一个非常相似的案例，但是stacktrace却大不相同:
I recently encountered a very similar case, but the stacktrace is quite different:

推荐答案
这似乎是由 JRE 问题引起的:
This seems to be caused by a JRE issue:
http://hg.openjdk.java.net/jdk/jdk/rev/01d8eae542ff
https://bugs.openjdk.java.net/browse/JDK-8218889
它被修复了
- 11.0.8 b01
- 11.0.7 b04
- 8u261 b05
您使用的是受影响的 JRE 版本吗?
Are you using an affected JRE version?
关于你提到的第二个问题:
As for the second issue you mentioned:
https://bugs.openjdk.java.net/browse/JDK-8241248
这是一个选项问题(但提到了一个解决方法).
This is an option issue (but mentions a workaround).
请研究这两个问题，尝试更新以解决第一个问题，看看您是否可以应用变通方法，只要第二个问题没有可用的修复.
Please look into both issues, try to update for addressing the first issue and see if your can apply the workaround as long as no fix is available for the second issue.
