Felix,
A test program is attached. If run without any changes, no events are
received by the framework listener.
If you comment out the first start and shutdown in the main method, one
event is received. If felix.shutdown() is not called inside
shutdownFelixRuntime, the event is received even with the new Felix
instance.
Thank you...
Regards,
Rajini

Hi Rajini,
Then it is strange, that it is not called ...
Do you have some sample code you might share for a quick code review ?

Felix
