Apache Tomcat 升级到 8.5.51 导致 400 错误

Question

将 Tomcat 从 8.5.50 升级到 8.5.51 时遇到问题。自从迁移到此版本后，发送到 http 端口的请求失败并显示 400 错误代码（错误请求）。 server.xml 配置为将 http 端口重定向到 https 端口。这已经工作了多年，直到升级才开始失败。下面是连接器配置和用于向服务器发送测试事务的 java 类。

我已经搜索了更改日志，我看到的唯一可能导致此问题的更改是针对错误 63966 的错误修复 - TLS 消息的字符集被硬编码为 ISO-8859-1。此错误修复已引入 8.5.51。我认为这可能是原因是当我们将此请求发送到 tomcat 8.5.50 时，回复 Content-Type 将如下所示：

内容类型：text/plain;charset=ISO-8859-1

使用 tomcat 8.5.51，我得到了这个： 内容类型：text/html;charset=utf-8

任何想法为什么我在升级到 8.5.51 及更高版本时收到 400 错误？

连接器配置：

修复它。显然 8.5.51 的 tomcat 不喜欢用 \n 终止标头。我将所有标题行终止符更改为 \r\n，现在我得到了 200 个成功代码。
