> I am experiencing huges memory leak when I install a feature which refresh a lot of bundles.
> After analysing several heapdump, these leaks seem related to KARAF-5506 : The class SecuredSessionFactoryImpl has a ThreadLocal<> serviceVisibleMap referencing all services used by commands, and this map is not cleaned when a service is removed (at least, I didn't see who is responsible to clean this map)
> Every time a service changed, a new entry is added to this map. Moreover, if a bundle is refresh, the classloader associated with the old bundle is keep in memory because of this map
