org.infinispan.container.entries.InternalNullEntry
Internal null cache entry used to signal that an entry has been removed but it's in the process of being removed from another component, i.e. an async cache store. This entry helps deal with situations where an eventual removal is under way. @author Galder Zamarreño @since 5.2


   @Override
   public InternalCacheEntry remove(Object k) {
      InternalCacheEntry e;
      if (isAsyncStore) {
         e = entries.replace(k, new InternalNullEntry(asyncStore));
      } else {
         e = entries.remove(k);
      }
      return e == null || (e.canExpire() && e.isExpired(System.currentTimeMillis())) ? null : e;
   }
