Spring Cloud Netflix Hystrix (Finchley.M2) is incompatible with Spring Boot Actuator (2.0.0.M4)

[juergenzimmermann]

As soon as I add org.springframework.boot:spring-boot-starter-actuator in build.gradle I'm getting the following log output when I start a microservice based on Spring Boot, Spring Webflux, Spring Data MongoDB, Spring Security Webflux etc.

Finchley.M2 was meant to work with Boot 2.0.0.M3. We recently just started looking at upgrading to the latest Boot milestone and realize there are some breaking changes. We will address these soon.

@ryanjbaxter any luck / progress so far ? spring-boot 2.0.0.RC1 is out recently

@n0mer We've had 4 more milestones since. M6(announcement pending) works with RC1. Next time please ask on gitter, not a closed issue.

@spencergibb ok

Starters for Eureka still on M2 (http://repo.spring.io/milestone/org/springframework/cloud/spring-cloud-starter-eureka/ , http://repo.spring.io/milestone/org/springframework/cloud/spring-cloud-starter-eureka-server/), hence was my question
