Spring Boot 2.1.4.RELEASE from time to time, receiving error: 2021-06-03 08:12:51.663 ERROR 3601 --- [10001-exec-2223] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.NullPointerException] with root cause
java.lang.NullPointerException: null
And that is all. No stack trace. We use Log4j2 logging with params: logging.level.root=error logging.level.org.springframework.boot=error logging.level.org.springframework.web=error
It is Rest application. All controllers have integration tests.

Spring Boot 2.1.4.RELEASE is EOL so please upgrade to a supported version at your earliest convenience. Putting the logs in ERROR reduces the chance of getting additional context. You should try DEBUG on the web package at least. If you can reproduce the problem with a supported version of Spring Boot, please share the additional logs.
