DefaultCacheManager.removeListener throwing NPE when server stopped
-------------------------------------------------------------------

Project: Infinispan
Issue Type: Bug

I'm seeing a NPE when Memcached server shutdowns:

The origin seems to be in ISPN-771
Maybe since transaction table now removes the listener, it needs to stop *before* the
cache manager notifier does?
