Description
Hi;
I'm using framework 5.6.1 (which uses resolver 1.10.0).
We are refactoring an old application which have problems, and while debugging (with felix.log.level=4), I got the following null pointer in the Candidates.remove method:
Here is the NPE (I don't see the NPE with felix.log.level=1)

I don't know if the NPE above has already been fixed, maybe in FELIX-5389 ? I tried to rebuild the latest framework and resolver from the trunk, but I'm getting a compilation issue:
[ERROR] /tmp/xx/framework/src/main/java/org/apache/felix/framework/ResolveContextImpl.java:[44,8] org.apache.felix.framework.ResolveContextImpl is not abstract and does not override abstract method getSubstitutionWires(org.osgi.resource.Wiring) in org.apache.felix.resolver.FelixResolveContext
