SpringBoot Hazelcast Cache Metric Error with Spring Boot 2.0.2

Hello everyone,

I've just upgraded Spring Boot from 2.0.1 to 2.0.2 and now our application doesn't startup anymore because of a NoSuchMethodError in the actuator metrics module.

Caused by: java.lang.NoSuchMethodError: com.hazelcast.spring.cache.HazelcastCache.getNativeCache()Lcom/hazelcast/core/IMap;

I assume the error is related to the type cast which was removed in this commit in HazelcastCacheMeterBinderProvider: https://github.com/spring-projects/spring-boot/commit/c826310fd1bb69dcc7df151a1992f39219565276#diff-733fa2b8acbd48ce952884562aef69a4

Thanks in advance.

@Koizumi85 Thanks for report. I've edited your description to replace "guys" with "everyone". While it may seem a small thing, some people feel excluded by "guys" and we don't want them to.

What version of Hazelcast are you using? A binary incompatible change was made in 3.9.4 which means that Spring Boot 2.0.2 requires 3.9.4 and 2.0.1 requires 3.9.3 (or earlier).

@wilkinsona Thanks for the hint. I wasn't aware, that we set a specific hazelcast version in our gradle file. Removed it and it works with the boot-managed version like a charm. :+1:

Excellent. Thanks for following up.

this issue again back with Hazelcast 4.2.1 combined with springboot 2.2.9 @wilkinsona

Comment From: snicoll

@ravichappa22 I don't think that's accurate considering that Spring Boot 2.2.9 manages Hazelcast 3.12.8. You can't expect to be able to switch to a new major version of Hazelcast that didn't exist when this version of Spring Boot was relased.
