Hi,
The bundle usage counting is required for a simple feature start and stop
functionality.
If a bundle is used by multiple features I need a count to know when to install and start a bundle
and when features are stopped to detect when to stop and or uninstall a bundle.

Depends what you mean by "bundle usage".
If you’re talking about services, then you can get the ServiceReferences
registered by a bundle and count the using bundles with getUsingBundles. If
you’re talking about package wiring and Require-Bundle then you can adapt the
bundle to a BundleWiring object and call getProvidedWires. Bear in mind that
there will be duplicates and the bundle could also wire to itself (or reference
its own services).

Hi,
Is there an existing ability in the OSGi environment to keep a bundle usage
count?
It is not difficult to create my own method and storage, but if something
already exists!
I did think I could use the Bundle data area but it seems that different
frameworks lay it out differently.
Aries subsystems has bundle counting but it is a bit heavy for my use case.
Any suggestions?
