Jenkins 在应用或保存配置时失败

Question

关于詹金斯版本。更改作业配置（授权矩阵）后 1.598 应用或保存失败并出现此错误：

Answer 1

完整调用堆栈实际上包括对 tomcat connector Http11Nio2Protocol.

的引用

当 Jenkins 由 Tomcat8（使用 JDK7 或 JDK8）管理时和 Http11Nio2Protocol，似乎有一个大小限制会触发连接器使用的异常SSL.

但只需将连接器更改为 Http11NioProtocol 即可使该限制消失。

这个有效：

<Connector port="9443" protocol="org.apache.coyote.http11.Http11NioProtocol"
           maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
           keystoreFile="D:/CI/jdk-7u65-windows-x64/jre/lib/security/cacerts" 
           keystorePass="xxx" keystoreType="JKS" 
           clientAuth="false" URIEncoding="UTF-8" keyAlias="yyy" />

也就是Http11NioProtocol，不是Http11Nio2Protocol。
