I think I have seen a similar issue years back. The difference between
launchpad and the feature launcher is that launchpad is invoking
ManagementFactory.getPlatformMBeanServer()
on startup, and I think back then adding that line to the launcher
solved my issue.
But my memory might also play tricks on me...

Hey Sling Team,
I'm scratching my head a bit on this one, but I'm seeing strange behavior
with the JMX Mbeans when using the Feature Launcher.
When I connect to the JMX console on an Apache Sling instance running on
the Feature Launcher via JConsole none of the Felix or OSGi MBeans appear
on an instance running via the Sling Launchpad.

It's especially weird since I am seeing log messages indicating that the
JMX MBeans are being registered. I tried creating a custom configuration
for org.apache.felix.hc.core.impl.CompositeHealthCheck:
{
"filter.tags:String[]":[
"systemalive"
],
"hc.name":"alive",
"hc.tags:String[]":[
"slingcmsalive"
],
"hc.mbean.name":"SlingCmsAlive",
"filter.combineTagsWithOr":false
}
And I see the Felix Health Check API registering the Health Check:

But nonetheless, the MBeans are not showing up via JConsole. As far as I
can tell, dependencies should be identical as I created the Feature Model
based on the Provisioning Model.
Any ideas? Anyone else using the Feature Model seeing anything similar?
Thanks,
Dan
