anything to github yet)
I'm trying to inject a SystemMBean into a DS component. When I try
this, loading the feature holding the component, fails with an error
message:

Does anyone know what I might be missing?
What I have done, is:
1. Add org.apache.karaf.system.core as a provided dependency
<dependency>
<groupId>org.apache.karaf.system</groupId>
<artifactId>org.apache.karaf.system.core</artifactId>
<version>${karaf.version}</version>
<scope>provided</scope>
</dependency>
2. Add a @Reference for the SystemMBean to the DS component
As a shot in the dark, I have also tried adding a
<feature>system</feature> dependency to the template feature.xml of my
feature (it shouldn't be necessary, but it was woth a try).
As far as I can tell, the "system" bundle is alive and loaded, and
exposes the service I'm trying to inject:
karaf@root()> bundle:list -t 1 org.apache.karaf.system.core
START LEVEL 100 , List Threshold: 1

service.bundleid = 46
service.id = 73
service.scope = singleton

org.apache.aries.jmx.whiteboard [18]
karaf@root()>
The org.apache.karaf.system.core bundle exports the
org.apache.karaf.system.management package:
Export-Package: org.apache.karaf.system;version="4.1.5",org.apache.kar
af.system.management;uses:="javax.management";version="4.1.5"
My bundle imports the org.apache.karaf.system.management package:
Import-Package: org.apache.karaf.system.management;version="[4.1,5)",o
rg.neo4j.graphdb,org.neo4j.graphdb.event,org.neo4j.graphdb.factory,or
...
Is there anything else I should check?
Thanks!
