We are not passing any value. The [default
configuration](https://github.com/jclouds/jclouds-karaf/blob/master/feature/src/main/resources/shell.cfg)
does not set the engine value, so "groovy" was used (which seems to be the
[right
value](https://github.com/groovy/groovy-core/blob/master/subprojects/groovy-jsr223/src/main/java/org/codehaus/groovy/jsr223/GroovyScriptEngineFactory.java#L44)).
I've also tried setting custom values there and directly instantiating the
javascript engine classes provided by the JRE, but both tests failed.

Yes. Well, there is no default constructor for that class; it requires the
BundleContext. I tried getting the context by calling the OSGI `FrameworkUtil`
to get and pass it to the engine. However, it couldn't load the engines. I'm
pretty sure I was doing something wrong here, as I don't know enough about OSGi
to be confident about what I was doing :)

I really don't know. Honestly, I've never used the interactive shell except for
installing features for other providers, so I have never tried. I don't know if
there were relevant changes that might have broken this.
BTW, regarding the shaded bundle fix, it works, but there is still this error
when the CLI starts:
