[ARIES-1443] After a restart the capabilities of a subsystem have changed (seem
correct) before the restart they seem wrong
This issue affects only newly installing features. The Subsystem service is
registered and added to the system repository before all of its capabilities
have been computed. Because
features implicitly export everything, their capabilities must be derived from
their content. This is currently done examining constituents and filtering them
based on the
Subsystem-Content header. It must be done this way for persisted subsystems,
which are unaffected by this issue.
Initially, I tried to fix the issue by looking for features in the INSTALLED
state as part of the modifiedService method of the SystemRepository because by
then the consituents have
been computed and all capabilities are available. Unfortunately, this will not
work for newly installing features with
apache-aries-provision-dependencies:=resolve and that remain
in the INSTALLING state.
Ultimately, the issue was fixed in BasicSubsystem by adding an additional path
to both getCapabilities and getRequirements. Newly installing subsystems can be
distinguished from
persisted subsystems by the presence of a SubsystemResource, which the former
will have while the latter will not. If a SubsystemResource is present, the
capabilities and
requirements can be computed from the content contained therein. This is
available as the newly installing subsystem is being added to the system
repository. Persisted subsystems
continue to function as before.
Note that this should also fix ARIES-1442.

> Feature subsystems should export all capabilities of its constituents. The
> osgi.identity capability is also exported but I doubt it is supposed to.
> It might cause problems when using osgi.identity in the preferred-provider
