Only in case the container exposes the jmx-exporter metrics endpoint by setting PROMETHEUS=true, the container should expose the port. Because the jmx-exporter is now disabled by default, this port has been removed from the expose list, so it does not get accidentially scraped by prometheus.

If you want to continue to use the jmx-exporter, you should expose the port in your deployment configuration.
