John Ross commented on ARIES-1441:
----------------------------------
Starting the subsystem is necessary for the following reason.
When the subsystems implementation bundle is stopped, a deactivation occurs. As
part of the deactivation, the root subsystem is stopped. As part of stopping
the root subsystem, the child subsystem is stopped. Because the child subsystem
references the bundle providing the necessary package, the bundle is stopped,
The issue does not occur if the subsystem is not started because (1) there is
no child subsystem to stop, and (2) protection against stopping unmanaged
bundles is already provided by line 147 of StartAction when stopping the root
subsystem.

> When performing a shutdown of the subsystem core bundle it tries to stop the
> framework because there is a org.osgi.util.tracker import package.
> Also in the same situation described above when trying to shutdown the
> framework by calling stop on bundle 0 it can fail with:
