Christoph Läubrich commented on FELIX-4260:
-------------------------------------------
At the time this issue was present I used Equinox 3.7 and Felic SCR 1.6
I then switched to the trunk version as suggested and didn't see the problem
any longer as far as I remember. I still see in the 1.8 line where operations
for DS components are executed outside the "Component-Thread" e.g. if services
are registered inside seperate threads or if CM updates take place. I'm just
not sure if this is an issue or is intentional.

> concurrent way, the IllegalStateException must be caught because it is
> possible that the service was already unregistered automatically in the event
> of an refresh/stop of the bundle.
