Since we updated Spring Boot from 2.1.6 to 2.3.0 (or 2.3.1) we are missing log output in Azure Application Insights. The logs are printed to stdout when running local. Deployed to an aks cluster, the logs are visible with "kubectl logs" but missing in the application insights.
Resetting the Spring Boot version to 2.1.6 lets the log reappear again.
This is the pom of the application (shortened)

The controller class:
@Slf4j
@RequestMapping("/xxx")
@RestController
public class LogController {
@GetMapping(value = "/logtest")
public String logSomething() {
log.debug("This is a DEBUG message");
log.info("This is an INFO message");
return "hallo hallo";
}
}
Finally the AI-Agent.xml file:
<?xml version="1.0" encoding="utf-8"?>
