The simplest spring boot app created using start.spring.io, without no further changes to it. 3 dependencies are added spring-boot-starter-actuator, spring-boot-starter-web and spring-boot-devtools.
Spring Boot 2.4.0, 2.2.0 - org.springframework.boot metrics not visible
Spring Boot 2.1.0 or previous release - works
Behavior is same in jdk 11 and 15, macOS Catalina and windows.
'/actuator' path is accessible
But org.springframework.boot metrics not visible from JConsole or VisualVM when connected
What could it be for for significant change of behavior?
