Amichai Rothman commented on KARAF-3973:
----------------------------------------
Here are the errors I found in the karaf log. The last one looks like it's the
refresh command. After the karaf restart, when my bundle is activated and works
properly, I still see the first error, but the second and third one are gone
and all works well.

> Bundles refresh doesn't work (bundles not resolved)
> ---------------------------------------------------
>
> Key: KARAF-3973
> URL: https://issues.apache.org/jira/browse/KARAF-3973
> Project: Karaf
> Issue Type: Bug
> Components: karaf-core
> Affects Versions: 4.0.1
> Reporter: Amichai Rothman
> Priority: Critical
>
> I have a bunch of bundles copied into the deploy folder of a fresh karaf
> 4.0.1 installation. The first time karaf runs, the bundles are not properly
> resolved, and apparently this has to do with the order in which they are
> loaded, i.e. if A depends on B and A is loaded first, then when B is loaded
> it is properly resolved but A never gets resolved. running the refresh
> command from console does not help either. However, if karaf itself is
> restarted, then everything is resolved and activated with no problem.
> In Karaf up to 3.0.3 this was not an issue - the moment B was loaded, even on
> the first time Karaf is run, A would automatically get resolved/activated as
> well. on 3.0.4 I get a deadlock on startup, so can't really tell if it works
> (see KARAF-3941). on 4.0.0 I haven't tried. 4.0.1 is the current reported
> issue.
