Guillaume Nodet resolved ARIES-1498.
------------------------------------
Resolution: Fixed
Assignee: Guillaume Nodet
Fix Version/s: blueprint-core-1.6.0
I think the setSatisfied might be called after stop() because I'm not sure
about the concurrency in the OSGi framework for the ServiceListener being
called and its removal.
I've added the volatile keyword and also an additional check.
