> NetBeans unit tests in the org.netbeans.core.osgi module pass but print a lot of stack traces when run against Felix 4.0.2:
> Apr 23, 2012 7:06:57 PM org.openide.util.lookup.implspi.ActiveQueue$Daemon run
> WARNING: Cannot process org.openide.util.WeakListenerImpl$ListenerReference@1ce1bea
> java.lang.NullPointerException

> 	at org.openide.util.lookup.implspi.ActiveQueue$Daemon.run(ActiveQueue.java:185)
> (The ActiveQueue thread in this case is looking for listeners attached via weak references which have since been collected, so that the stub listener can be cleanly detached from the observable object. It is impossible to guarantee exactly when this cleanup will run.)
> Presumably BundleRevisionImpl.m_wiring is null. searchImports should I think just treat this as if result==null. Can offer a patch if you like.
