Apache Karaf 5 and Decanter for overall observability
summary
Karaf 5 is a refactor that removes OSGi core and replaces it with a service loader/registry, a builder API, and core config and lifecycle services; it supports multiple application managers so it runs Spring Boot and OSGi side-by-side and loads services via a classpath protocol. Packaging supports fat-jar deployable images or traditional archives, works with Kubernetes ConfigMaps, and Decanter (an OSGi monitoring app) can collect JMX and application metrics from both OSGi and non‑OSGi apps out of the box; MVP and first RC target follow-up development.
