> When deploying features _via_ the drop-in mechanism (using the {{FeatureDeploymentListener}}), it also installs needed bundles, as required.
> But when the feature file is removed from the deploy directory, some problems may occur, the most important being that bundles installed by the feature (only) will not be uninstalled.
> An exception is thrown when trying to access the feature bundle entries when not permitted, resulting in an exception, 
> I think this is related to what's said in the revision 909487 comment (http://svn.apache.org/viewvc?view=revision&revision=909487).
> That snippet of the class
> 142 } else if (bundleEvent.getType() == BundleEvent.UNINSTALLED) {
> 143 	try {
> 144 	Enumeration featuresUrlEnumeration = bundle.findEntries("/META-INF/" + FEATURE_PATH + "/", "*.xml", false); 
> will always throw an exception as the findEntries has to throw an IllegalStateException if the bundle in uninstalled.
> Therefore, the call to "featuresService.uninstallFeature(f.getName(), f.getVersion()); " is never reached, and bundled participating in that feature are not uninstalled.
> It's worth noting that in some cases everything is correctly removed, but that seems to happen only if Karaf has been restarted after the first drop-in of the feature.
