tomcat8 使用 stock http - 读取请求时出错，已忽略

Question

stock ubuntu 18 在 digitalocean VM 上，stock jdk & tomcat，stock server.xml：每次 http 客户端尝试连接时都会得到这个（我在尝试使用 https 时遇到其他错误，所以尝试恢复到 http 并现在得到这个）

系统版本：

错误如下：

这里是 server.xml 部分（同样，generic/stock）

<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" />
<!-- A "Connector" using the shared thread pool-->
<!--
<Connector executor="tomcatThreadPool"    
           port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" />
-->

google 似乎对此一无所知？

似乎是同一个问题：

This issue happens because tomcat8/8.5.30-1 was built with OpenJDK 9 and can no longer run with OpenJDK 8 due to the use of new java.nio.ByteBuffer methods.If you switch to OpenJDK 9 to run Tomcat the issue should go away. I'll make tomcat8 runnable again with OpenJDK 8 in the next update.

Tomcat 8.5.31 已经 released but hasn't made its way in the ubuntu 包。
