Using v1.4.1 of Spring Boot
When attempting to set the sensitivity of all actuator endpoints to sensitive, mainly to make the health check endpoint sensitive, i set the property "endpoints.sensitive" to "true" to set all endpoints as sensitive. After making this change, calling the health endpoint did not just show UP/DOWN status but still status of all known services. I had to explicitly set the property "endpoints.health.sensitive" to "true" to get just UP/DOWN status on health check endpoint.
