Hello,

I'm trying to use event admin in my wisdom project, but i have some problems with @subscriber from org.apache.felix.ipojo.handler.eventadmin.

All my components are valid and event admin sending and receiving works, but if I try to go on monitor url : http://localhost:9000/monitor/ipojo/, I have an empty list of Instances, Factories, Handlers. All other urls (bundles, controller, services, ...) work fine in the monitor.

If I use only : org.osgi.service.event.EventHandler to handle event admin and I remove @subscriber, all urls work fine.

And I have an error in wisdom trace when I try to access at the url : http://localhost:9000/monitor/ipojo/,
@subscriber component seem malformed.

Wisdom version : 0.7.0

Error trace :

[ERROR] o.w.f.v.HttpHandler {vert.x-eventloop-thread-0} - Cannot render the response to /monitor/ipojo.json

I may be related to https://issues.apache.org/jira/browse/FELIX-3836 (which should have been fixed already). If it's not this, it's a bug in the event admin handler. Gonna have a deeper look,

It's maybe the same problem, but I already use org.apache.felix.ipojo 1.12.1 and org.apache.felix.ipojo.handler.eventadmin 1.8.0

The problem is only present in the @subscriber, @Publishes works fine.
