--------------------------------
Resolution: Invalid
> NPE in Resolver checkPackageSpaceConsistency
> --------------------------------------------
>
> Key: FELIX-5998
> URL: https://issues.apache.org/jira/browse/FELIX-5998
> Project: Felix
> Issue Type: Task
> Components: Resolver
> Affects Versions: resolver-2.0.0
> Reporter: Pierre De Rop
> Priority: Major
>
> I'm using a custom ResolveContext implementation that I've written in order
> to calculate the dependencies of some applications which bundles are all
> centralized in an OBR. Now, using the Felix framework 6.0.1 (and the Resolver
> 2.0.0 that is provided by the framework), I sometimes get an NPE in the
> ResolverImpl.checkPackageSpaceConsistency, line 1319).
> My OBR is not yet fully "curated" (I still have some " Candidate permutation
> failed due to a conflict between imports" logs when enabling
> felix.log.level=4). So I'm cleaning the OBR gradually, but now, sometimes I
> see this NPE while resolving :
> {code:java}
> java.lang.NullPointerException

> {code}
> The bad thing is that I'm not able to reproduce the NPE when I enable
> felix.log.level=4, and the NPE is difficult to reproduce.
> Could someone please give me a clue about what could produce this NPE ? Are
> there some traces which could be added in order to figure out what is the
> problem ? Then is there a fix which should be done in order to avoid this
> null pointer ?
> If I fully cleanup my OBR, maybe I won't have anymore the NPE, but I just
> wanted to report it here.
> thank you.
