Subject [jira] [Commented] (KARAF-4603) Nashorn support in Karaf
Date Tue, 27 Jun 2017 13:01:03 GMT

Guillaume Nodet commented on KARAF-4603:
----------------------------------------

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"                                                          15:00:24
Factory              jdk.nashorn.api.scripting.NashornScriptEngineFactory@35b56646
Context              javax.script.SimpleScriptContext@4130f92c

{code}

>          Components: karaf-osgi
>    Affects Versions: 3.0.7

> OpenJDK 8 64-bit

> 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.
