I'm not sure to understand why this would be related to packages and boot delegation.
On Java8, I can run the following on a bare karaf:
{code}
karaf@root()> ((($.context bundle 0) loadClass javax.script.ScriptEngineManager) newInstance) getEngineByName "js"
Factory              jdk.nashorn.api.scripting.NashornScriptEngineFactory@35b56646
Context              javax.script.SimpleScriptContext@4130f92c

{code}

> I can't use JavaScript scripting in Karaf on Java 8 because ScriptEngineFactory implementation (provided by Nashorn) is located in system package {{jdk.nashorn.api.scripting}}. In Java 7, Rhino implementation is located in package {{com.sun.script.javascript}}. By default, Karaf offers some system packages (including {{com.sun}}) in configuration property {{org.osgi.framework.bootdelegation}} which is defined in file {{etc/config.properties}}. That's why Rhino available from Karaf. It will be great if you add {{jdk.nashorn}} to boot delegation by default.
