Description Thomas Watson CLA 2011-06-09 17:13:37 EDT 
If a new bundle is being installed for which there already is an installed bundle with the same BSN/Version then the following will be done when org.osgi.framework.bsnversion=managed

In the bsn/version check we ask the find hooks, can the installing bundle
context see any of the collection of already installed bundles with the same
bsn/version as the about to be installed bundle.  In this case the
Collection<Bundle> will contain all the bundles with the requested BSN/version
of the about to be installed bundle.  If at the end of the bundle find hooks
call the Collection<Bundle> is empty then the install succeeds; otherwise the
insetall fails with a REJECTED_BY_HOOK BundleException.

Note that the find hooks are only consulted if "managed" is used.

patch and tests

Unfortunately it did not turn out to be feasible to use the bundle FindHook to accomplish this.  I needed to introduce a new bundle CollisionHook.  This patch does that in the existing org.osgi.framework.hooks.bundle package.  I am proposing this back to OSGi in RFC 174.  Note that this is provisional and very early work.  I am simply attaching the patch here so I don't lose the prototype work I have done so far.
Comment 2 Thomas Watson CLA 2011-08-04 14:29:07 EDT 
RFC 174 is moving forward.  I will revisit this patch and plan to get it ready for M2.

I merged an updated patch to master with:
