Richard S. Hall commented on FELIX-971:
---------------------------------------
It looks like ServiceTracker.close() was not called. When we stop a bundle, we
unregister all services, release any used services, and unregister any events
listeners for the bundle. This is the order that the spec says they should be
done. However, it appears like it might be the case that since the listeners
are removed last, that the unclosed ServiceTracker sees events after its
context is invalid. Can you verify if the ServiceTracker is closed and if not,
try to close it and see if it goes away?
