MeterRegistry throws BeanCreationNotAllowedException on shutdown #38240
Description
We use Micrometer with NewRelic in our Spring Boot 3.1.5 applications.
After migration to the newest Spring Boot we noticed that following WARN log always appears during application shutdown:
Failed to apply the value function for the gauge '{{custom_gauge_name}}'. The exception behind above log looks like:
`org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name 'entityManagerFactory': Singleton bean creation not allowed while singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)` App is integrated with NewRelic agent - i checked that mentioned exception is triggered when:
at com.newrelic.telemetry.micrometer.NewRelicRegistry.publish(NewRelicRegistry.java:168) at io.micrometer.core.instrument.push.PushMeterRegistry.publishSafely(PushMeterRegistry.java:67 at io.micrometer.core.instrument.push.PushMeterRegistry.close(PushMeterRegistry.java:135) at io.micrometer.core.instrument.step.StepMeterRegistry.close(StepMeterRegistry.java:156) at com.newrelic.telemetry.micrometer.NewRelicRegistry.close(NewRelicRegistry.java:157) Please note that similar bug for older Spring Boot 2.2 version was reported under #19557. I've reproduced reported bug: https://github.com/wojciechkedziora/spring-boot-3-19557 (check this comment for more details).
