最近我们面临一个问题，我们无法再在 Heroku 工作节点上启动 Spring Shell 应用程序。在 shell 应用程序启动后，控制台直接打印java.lang.NullPointerException一百万次（就像有一个循环试图实例化一个 bean 或者一直失败的东西）。
这是一段摘录：

我们使用 Spring Bootv2.6.4和 Spring Shell v2.0.1.RELEASE。Spring Shell 应用程序是容器化的（Docker），我们通常以以下方式启动它：
heroku run --type worker -a foo -- /env.sh java -jar ops.jar
你们有没有人有一些关于如何解决甚至如何进一步调试的提示或一些东西，即打印异常的整个堆栈跟踪？
这可能与无法JLine在 Docker 容器中与 Heroku 一起使用的方式相关吗？！然而，这在过去就像一种魅力。
如前所述，我们感谢有关如何进一步调试的任何提示或提示。
干杯
