[infinispan-dev] NPE in Lifecycle::cacheStopping

[Ales Justin]

I'm regularly seeing this NPE while undeploying my app / tests:

21:48:41,367 WARN  [org.jboss.msc.service.fail] (MSC service thread 1-10) MSC00004: Failure during stop of service jboss.capedwarf.cache-lifecycle.prospective_search.capedwarf-test: java.lang.NullPointerException

It doesn't break the app, hence just reporting NPE. :-)
