I am seeing a strange behaviour with the Felix Webconsole.

I build the latest snapshot from Github and started it. I initially noticed, that someone must have removed OSGi from the default standalone.xml (grrr), so I had to correct that first.

When I added the Felix Webconsole according to this, I noticed a few exceptions in the server log:

Going to the documented URL http://localhost:8080/httpservice/system/console gave me a HTTP 404!!

However, when going to http://localhost:8080/system/console I got the the Felix Webconsole.

Please be so kind and update the documentation!

Then I tried to get rid of the Exception above. I noticed that the Felix Webconsole seem to import org.osgi.service.metatype.MetaTypeProvider which is provided by the OSGi Enterprise Compendium and according to https://issues.jboss.org/browse/AS7-5803 this has been removed as a default capability.

So, I tried to add the enterprise compendium as capability and re-started JBoss AS. As expected, the Exception went away. However, it appears that although the Felix Webconsole bundle gets started, it does not bind to the HTTP Service (no corresponding message in the log about the context) and hence I see a HTTP 404 when going to the URL.

I follow the reasoning behind AS7-5803, however, how would I then correctly provide the org.osgi.service.metatype package to the Felix Webconsole? Who is the correct "implementor" of this API and hence would be the correct capability to be added?
