/*
* Tests the start level of bundle constituents.
*
* A managed bundle is a bundle that was installed via the Subsystems API
* either as content or a dependency. This includes the region context
* bundle. The life cycle of managed bundles should follow the life cycle of
* the subsystem of which they are constituents. They therefore receive a
* start level of 1 to ensure they will be started and stopped at the same
* time as the subsystem.
*
* An unmanaged bundle is a bundle that was installed outside of the
* Subsystem API. For example, the root subsystem may contain bundles that
* were installed prior to the subsystems bundle. It's also possible to
* install bundles via subsystem.getBundleContext().install(...). Unmanaged
* bundles retain the start level setting assigned by the framework or
* third party.
