If I recall, I don't think that should be null. It would be awesome if
there was some way to reproduce it.

Hi,
A user of ours just reported this stack trace with 3.0.7:
org.apache.felix.framework.resolver.ResolverImpl.permutateIfNeeded(ResolverImpl.java:1140)
org.apache.felix.framework.resolver.ResolverImpl.checkPackageSpaceConsistency(ResolverImpl.java:1066)
org.apache.felix.framework.resolver.ResolverImpl.resolve(ResolverImpl.java:176)
org.apache.felix.framework.FelixFelixResolver.resolve(Felix.java:4066)
org.apache.felix.framework.ModuleImpl.searchDynamicImports(ModuleImpl.java:1412)
org.apache.felix.framework.ModuleImpl.findClassOrResourceByDelegation(ModuleImpl.java:734)
Looking at the code in question:
SortedSet<Capability> candidates = allCandidates.getCandidates(req);
if (candidates.size()> 1)
{
it seems like there is no candidates set for the requirement which
causes the candidates.size() method to throw .. This is still the same
code in 3.2.2.
The user in fact reports that after a restart everything works fine.
Regards
Felix

I don't think anything changed in that area for 3.0.8, but you could try
it on 3.0.7 to see.
If it is reproducible, then open a bug and tell me how and I'll look
into it.
