There are no metrics jvm_* in the actuator/prometheus

[Monax111]

After update Spring(2.4.2 -> 2.5.0) i can't see jvm metric by url
http://localhost:8080/application/actuator/prometheus
dependency report: https://scans.gradle.com/s/aof3kiwqv7mae
i start debugging and found some interesting:
MeterRegistryPostProcessor.postProcessAfterInitialization() - condition if (bean instanceof MeterRegistry) is never true.
I think problem in order. I mark some breakPoint:

1. created bean MeterRegistryPostProcessor.
2. execute method AbstractAutowireCapableBeanFactory.doCreateBean for bean PrometheusMeterRegistry
   2.1) created bean PrometheusMeterRegistry
   2.2) execute initializeBean() witch execute method applyBeanPostProcessorsBeforeInitialization(). In debbug mode i see, then in list of beanPostProcessor do not contains MeterRegistryPostProcessor
   proof:
   
   2.3) MeterRegistryPostProcessor.postProcessAfterInitialization() do not execute on bean PrometheusMeterRegistry.
3. Execute AbstractBeanFactory.addBeanPostProcessors() and in debuggin mode i see than MeterRegistryPostProcessor add to context
   

How i undersend problem: MeterRegistryPostProcessor do not add to context before created bean PrometheusMeterRegistry

Is there a chance this is a duplicate of #26630 ?
Could you check if 2.5.1 solves the issue in your application?
