This OSGi bundle exemplifies the minimal setup required to use the Nashorn JavaScript engine as an external script engine in Apache Sling.

Significant implementation details:

• embeds the Nashorn engine inside the bundle
• also embeds the transitive ASM depedndency to make the bundle fully self-contained
• uses a more recent ASM version for compatibility with recent JDKs
• exposes a servlet at /bin/nashorn that executes a simple script using the Nashorn engine
• obtains the ScriptEngineManager as an OSGi reference

Build with mvn install. Deploy with mvn sling:install. Test by accessing http://localhost:8080/bin/nashorn-test .
