> Deadlock on refrsh Import and refresh
> -------------------------------------
>
> Key: FELIX-2437
> URL: https://issues.apache.org/jira/browse/FELIX-2437
> Project: Felix
> Issue Type: Bug
> Components: Configuration Admin

> Environment: Felix framework 2.0.4
> Felix webconsole 3.0.0
> Sling
> Reporter: christian

> I encountred a Deadlock using Webconsole (s. stacktrace below)
> Stepps to reproduce:
> 1) in webconsole navigate to "bundles"
> 2) select and open the detail view of a bundle that has a lot dependencies (I used sling and as bundle the sling api bundle)
> 3) click "refresh package import"
> 4) click "refresh"
> It the request from 4) is processed while he one from 3) is still running, you get a deadlock.
> Found one Java-level deadlock:
