-----------------------------------

             Summary: [DS] Dependency manager can be active but not have m_bindMethods set
                 Key: FELIX-4224
                 URL: https://issues.apache.org/jira/browse/FELIX-4224
             Project: Felix
          Issue Type: Bug
          Components: Declarative Services (SCR)
    Affects Versions: scr-1.8.0
            Reporter: David Jencks
            Assignee: David Jencks
             Fix For: scr-1.8.0


We've seen an NPE from m_bindMethods being null in this code:

        public void addedService( ServiceReference<T> serviceReference, RefPair<T> refPair, int trackingCount )
        {
            m_componentManager.log( LogService.LOG_DEBUG, "dm {0} tracking {1} MultipleDynamic added {2} (enter)", new Object[] {getName(), trackingCount, serviceReference}, null );
        	boolean tracked = false;
            if ( getPreviousRefMap().remove( serviceReference ) == null )
            {
                if (isActive())
                {
                    getServiceObject( m_bindMethods.getBind(), refPair );


(DependencyManager.MultipleDynamicCustomizer, around line 314)

After some investigation I can't see any way this can occur except from m_bindMethods not being volatile.  I'll see if this reoccurs after making it volatile.
