This is fairly complicated to explain, but here goes.
I am trying to understand what the behaviour should be in the
following circumstance:
- bundle A exports a package and is used by bundles B, C and D
- bundle E exports a package with the same name and is not used by any bundle
- A new repository.xml is deployed using OBR with an updated version
of bundle A *without* the exported package
My observation is that:
- Two versions of bundle A now exist
- All the previous wirings are retained to the package in the old
bundle are retained. Similarly, existing package wirings to other
packages are also retained
- Bundle E is not used, still.
- The new version of the bundle "may be" used for some package
wirings, but not worked out the behaviour there yet.
Does this sound correct? And am I correct in thinking the problem was
in originally having a split package?
Now, in more detail and with proper bundle/package names:
I have a bundle `com.elsten.bliss.platform`. Here are the wirings before update:

Now I update, which updates the bundle and a number of bundles
besides. I perform this with a _management agent_ coded by myself
which uses OBR to update the new bundle versions and then calls
refresh.
After this occurs, I set a breakpoint in
`com.elsten.bliss.main.PlatformImpl` so I can test the wirings again.
I expect that the old `com.elsten.bliss.main.Platform` has been
removed. However:

84|Resolved | 1|com.elsten.bliss.platform (28.1.3)

Now there are two versions! So I print the wiring (at this stage the
services are not wired so no point in including them):

So the new bundle is barely being used for anything.
My suspicion is that it's something to do with the withdrawal of the
`com.elsten.bliss.licence` package. This was removed, but note that
this always existed (before the update):
---
g! lb licence
START LEVEL 1
ID|State |Level|Name
69|Active | 1|com.elsten.bliss.licence (1.0.1)
g! inspect capability osgi.wiring.package 69
com.elsten.bliss.licence [69] provides:
---------------------------------------
osgi.wiring.package; com.elsten.bliss.licence 1.0.1 [UNUSED]
---
Any help with understanding this would be greatly appreciated. Also,
ways of getting out of this mess.
Thanks,
Dan
