Re: NPE with felix framework 3.0.8
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.

I try to get hold to a system which exhibits this problem and try to
find out how to reproduce ...
At the moment it looks like this:
* start framework
* after startup install and start a bunch of bundles
* use the system
--> NPE occurs
* stop framework
* start the framework again
--> all bundles already installed and starting properly
* use the system
--> works flawlessly without NPE
So it sounds like an issue related to resolution bundles installed after
startup.

Re: NPE with felix framework 3.0.8
Posted by "Richard S. Hall" <he...@ungoverned.org>.
If I recall, I don't think that should be null. It would be awesome if
there was some way to reproduce it.
