> The {{/solr/admin/info/system}} endpoint, used by the Solr Operator for
> start-up and liveness probes, can fail if response times are excessive. This
> update optimizes the addMXBeanMetrics method by skipping unreadable
> properties earlier, minimizing exceptions and boosting performance. This
> leads to more efficient MBean metric collection, enhancing monitoring and
> diagnostics.
