Valentin Valchev resolved FELIX-3426.
-------------------------------------
Resolution: Fixed
fixed in svn rev.1309002
> UPnP Plugin device tracking is error-prone
> ------------------------------------------
>
> Key: FELIX-3426
> URL: https://issues.apache.org/jira/browse/FELIX-3426
> Project: Felix
> Issue Type: Bug
> Components: Web Console
> Affects Versions: webconsole-upnp-plugin-1.0.0
> Reporter: Valentin Valchev
> Assignee: Valentin Valchev
> Priority: Critical
> Fix For: webconsole-upnp-plugin-1.0.2
>
>
> Sometimes, when one device appears, and another is removed, the plugin is
> unregistered. The reason is that the addingService() and removedService() in
> the activator are not synchronized.
> In addition, in removedService() the code fragment is absolutely incorrect:
> if (tracker.getTrackingCount() == 0 && plugin != null)
> {
> plugin.unregister();
> this.plugin = null;
> }
> The reason is that 'tracking count' is always incremented - no matter if a
> service is registered, modified or unregistered. It is NOT the count of
> tracked services.
