> NPE in MultiplePrototypeRefPair.unsetServiceObject
> ---------------------------------------------------
>
> Key: FELIX-5950
> URL: https://issues.apache.org/jira/browse/FELIX-5950
> Project: Felix
> Issue Type: Bug
> Components: Dependency Manager Runtime
> Environment: Mac OS X 10.14
> Reporter: Olivier Prouvost
> Priority: Major
>
> 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)
>
