J.W. Janssen commented on FELIX-4184:
-------------------------------------
Unlike to what Marcel said, DA *is* stopping affected bundles, at least, it
should do that if I read the StopBundleCommand#omitBundleStop() method
correctly.
However, that method contains a flaw, as it retrieves the bundle information
*twice from the same* (source) DP, instead of once from the source DP and once
from the target DP. Hence, the "sameVersion" boolean always equals to "true",
causing *none* of the affected bundles to be stopped. This might explain the
resolver problems (partly).
If we would fix this issue, then the affected bundles will be stopped during
the installation of a DP, but I'm not sure yet whether this would also prevent
any resolver issues...

> URL: https://issues.apache.org/jira/browse/FELIX-4184
> Project: Felix
> Issue Type: Bug
> Components: Deployment Admin
> Affects Versions: deploymentadmin-0.9.4
> Reporter: Marcel Offermans
>
> When you use the system property to not stop the world during an update,
> updating a running bundle might cause a (temporary) resolver error (I've seen
> it throw exceptions related to uses constraints). According to the spec, if
> we get an exception here, we should rollback. If you stop the world, this
> never happens, but here such temporary exceptions are probably resolved when
> we refresh packages at the end. That does not happen though, since we never
> get there. We should consider covering this use case, letting the deployment
> continue and deal with errors when resolving (and maybe then rolling back).
