resilience4j: CircuitBreakerEvents not Publishing to CircuitBreakerEvents Endpoint.

After configuring the spring property management.endpoint.circuitbreakerevents.enabled=true there is no output on either success or error events.

Here are my configuration properties for test…

...
management.endpoints.web.base-path=/server
management.endpoints.web.exposure.include=*
management.endpoint.health.show-details=always
management.health.defaults.enabled=true
management.health.circuitbreakers.enabled=true
management.endpoint.circuitbreakerevents.enabled=true
management.metrics.distribution.percentiles-histogram.http.server.requests= true
management.metrics.distribution.percentiles-histogram.resilience4j.circuitbreaker.calls= true

resilience4j.circuitbreaker.backends.wcw.record-exceptions=org.springframework.ws.client.WebServiceIOException
resilience4j.circuitbreaker.backends.wcw.ignore-exceptions=

The output for the endpoint config at /server/circuitbreakers shows status up and working…

{
  circuitBreakers: [
  "wcw"
  ]
}

A MockMVC Response confirms the the CircuitBreaker recorded a failed event. However, the ouput at /server/circuitbreakerevents/wcw is empty.
