当春季启动版本为1.5.3.RELEASE时，启动应用程序时出现以下错误

堆栈跟踪：

注意：当版本更改为1.4.2.RELEASE时，它可以正常工作，并且没有引发上述异常

我的代码抛出异常如下

我的spring-boot版本是2.1.7.RELEASE，嵌入式tomcat用于运行应用程序。我也设置了属性server.connection-timeout=30s

我几乎到处搜索都无法找出这个问题的根本原因。我还捕获此异常并将其打印在日志中并将响应作为 BAD_REQUEST 返回。

这个异常是间歇性抛出的，我的生产服务器此时消耗了 80% 以上的 CPU 和内存。

这实际上是一个 POST 请求，请求正文的验证如下 …
