在我们的生产日志中，我们得到了以下非常长的堆栈跟踪：

和

java.lang.StackOverflowError: null
    at javax.servlet.ServletRequestWrapper.getAsyncContext(ServletRequestWrapper.java:435) ~[tomcat-embed-core-9.0.44.jar!/:4.0.FR]

不幸的是，我无法在本地或测试中重现此行为。在堆栈跟踪中没有引用我们的应用程序代码。所以也许这是弹簧引导与嵌入式tomcat和华夫饼相结合的配置问题？目前我们正在结合使用 Spring Boot 2.4.4 和 Java 11 以及 Angular 10。

异常似乎也不是由用户交互直接引起的（检查访问日志）。我已经尝试了不同版本的框架，但没有成功。

有任何想法吗？
