> I use Felix with the eclipse runtime (Photon 0918), and I get a NPE when running my application. 
>  
> Actually in the code of 
> MultiplePrototypeRefPair.unsetServiceObject we have :  instances.get(key). 
> If we search for the callers, the DependencyManager class call It like this : 
>  
>        protected void ungetService(RefPair<S, T> ref)
>         {
>             Object service = ref.unsetServiceObject(*null*);
>             if (service != null)
>  
> Unfortunately, the instances map is a ConcurentHashMap which can not deal with null keys (it calls key.hashcode at the beginning), and this call will always raise an exception... 
> Don't know what is the Felix version involved, but the bundle I use in my launch configuration is  (org.apache.felix.scr 2.0.14.v20180117)
