OSGi and Java 9+
summary
Java 9’s JPMS forces concrete changes: OSGi Core R7 adds multi-release bundles (manifest multi-release handling, supplemental manifests and nested multi-release jars), runtime discovery of system packages via the Java API, and import support for java. packages; Bnd still needs updates to generate those artifacts. Experiments show mixed results: the “OSGi sandwich” fails on unnamed-module accessibility and was too brittle, while the Atomos approach (convert bundles to modules, JLink+Moditect image*) can build a runnable image and launch a GoGo shell.
