To be able to interact with the custom `SimpleMBean` at run time, you need to provide Native Image with additional [dynamic-proxy metadata](../ReachabilityMetadata.md#reflection) for the MBean interface. For this, create or modify a JSON file named _reachability-metadata.json_ with the following contents:
