Richard S. Hall resolved FELIX-952.
-----------------------------------

       Resolution: Fixed
    Fix Version/s: felix-1.6.0
         Assignee: Richard S. Hall

I modified ServiceRegistry.unregisterServices() to check to see if the registration is valid before calling unregister(), so I think this should solve your issue. Please close this issue if you are satisfied.

> I have a bundle which happens to unregister some services from a ServiceListener.
> What happens is that when the bundle is stopped, ServiceRegistry#unregisterServices(Bundle) is called.
> This method unregister services one by one.   When one service has been unregistered, my listener is called which unregister another service.
> When the loop iterator to this very service, an exception is thrown.
> {code}
> Caused by: java.lang.IllegalStateException: Service already unregistered.
