             Summary: NPE in ResolverImpl
                 Key: FELIX-5015
                 URL: https://issues.apache.org/jira/browse/FELIX-5015
             Project: Felix
          Issue Type: Bug
          Components: Resolver
    Affects Versions: resolver-1.6.0
            Reporter: Alexandre Roman


The method getPackageSources in ResolverImpl.java returns a Set.
This collection is used in mergeUses (line 1039) in a foreach loop.

A null value may be returned by getPackageSources, as a result of querying a 
Map. In this case, the foreach loop in mergeUses will trigger a NPE.

The method getPackageSources should return an empty Set when there is no result.
