Glyn Normington commented on ARIES-870:
---------------------------------------
I've noticed an issue when running the Aries subsystems implementation in the
Virgo user region (!) which may be relevant. Here's a portion of a stack trace:
Caused by: org.osgi.service.subsystem.SubsystemException:

The strange thing is that hello.jar doesn't need the osgi.ee capability (nor
does it use BREE). Also, the system bundle is, of course, already resolved and
there's only one system bundle in my system, so it's strange that the Felix
resolver can't resolve it.
I'm not complaining about this stack trace - running inside the Virgo user
region is likely to be the problem (as the user region doesn't allow any
generic capabilities of the system bundle to be visible) - but it *may* help to
inform the current issue.

> Project: Aries
> Issue Type: Bug
> Components: Subsystem
> Reporter: John Ross

> When working with the Resolver in order to compute dependencies and resolve
> subsystems, the ResolveContext will need to handle requests for osgi.ee
> capabilities. Currently, these capabilities need to be provided by resources
> packaged with the subsystems.
