Christian Schneider commented on KARAF-1715:
--------------------------------------------
Here is another stack trace of a thread that may be involved.
So it seems because of the waitForInit the activator thread does not return. As
the activator probably already locked the bundle the config admin thread above
will not succeed. So the waitForIntit can also not succeed.

> Occasional freeze on feature:install webconsole

> Key: KARAF-1715
> URL: https://issues.apache.org/jira/browse/KARAF-1715
> Project: Karaf
> Issue Type: Bug
> Components: karaf-webconsole
> Affects Versions: 3.0.0.RC1, 3.0.0
> Reporter: Ioannis Canellos
> Priority: Critical
>
> This is not something that happens all the time, so it might require a couple
> of attempts in order to reproduce it.
> On a clean Karaf container feature:install webconsole can freeze and never
> return. When this happens CTRL-C does not stop the command execution and the
> only way to recover is a restart of the container.
