Alexander Klimetschek commented on FELIX-4520:
----------------------------------------------
Same here, together with an NPE in ServiceReferenceImpl. ARIES-955 seems to be
related.
Happened while developing a BundleListener that sometimes threw exceptions (not
sure if related) and continuous start/stop/update/install/uninstall of bundles.

> I've got this NPE while updating a bundle in deploy folder (I'm running my
> staff under Karaf 3.0). Occurs in the following excerpt of
> org.apache.felix.framework.resolver.ResolverImpl - wire.getProviderWiring()
> is null
> // Wrap the capability as a hosted capability if it comes
> // from a fragment, since we will need to know the host.
> BundleCapability c = wire.getCapability();
> if
> (!c.getRevision().equals(wire.getProviderWiring().getRevision()))
> {
> c = new WrappedCapability(
> wire.getProviderWiring().getRevision(),
> (BundleCapabilityImpl) c);
> }
>
> Initial startup of the system goes without problems. Let me known if some
> more details required from my side.
> *Update*: I suspect the problem is cause by another thread running in
> parallel and setting wiring to null. I did not notice any synchronization
> between fileinstall and FelixFrameworkWiring thread and later one may set
> m_wiring to null after fileinstall has checked it to be not null.
