>
> If a bundle install another bundle using his Bundlecontext, when the FeatureService resolve a features, then a BundleException can be thrown by the osgi framework.
> FeaturesServiceImpl, in the method 'resolveBundles' registers a ResolverHookFactory and unregisters this factory at this end. However, if another bundle X is resolved during the execution of this methods (using a BundleContext), then this ResolverHookFactory will be used, and it can be unregistered during the resolution of X. The osgi spec says that the resolution of X should fail if a ResolverHookFactory is unregistered during the resolution.
> This can happens on a cold start when "fileinstall" install a bundle and the FeatureService installs the boot features.
