> Key: FELIX-4012
> URL: https://issues.apache.org/jira/browse/FELIX-4012
> Project: Felix
> Issue Type: Bug
> Components: Web Console
> Affects Versions: webconsole-upnp-plugin-1.0.2
> Reporter: Valentin Valchev
> Assignee: Valentin Valchev
> Fix For: webconsole-upnp-plugin-1.0.4
>
>
> Since OSGi r4.3 it he methdod UPnPDevice.getIcons() may throw
> IllegalStateException if you keep reference to device that has been removed
> from the network.
> During startup the ServiceTracker will notify the plugin for all previously
> registered UPnP devices. While processing them, a device can be removed and
> the reference becomes obsolete. Then the getIcons() method will throw
> exception which is not caught and will cause the BundleActivator.start() to
> fail. So the bundle stays in resolved state.
> Here is stack trace of the problem:
> {code}
> java.lang.IllegalStateException: The UPnP Device was removed from the
> network. Device UDN: uuid:e516cbe4-35fd-4cf9-a862-886969e13050
