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


This issue is currently scheduled for 3.5.x, but not 3.6. Should this issue be fixed in 3.6 as well (or instead)? If so, please correct the fix version(s).

Thanks,
Gail

> Store evictAll information in a separate infinispan cache instance in order to avoid doing stuff like this in BaseRegion.toMap which could be quite expensive in the context of SecondLevelCacheStatistics calculations:
>    public Map toMap() {
>       if (checkValid()) {
>          // If copying causes issues, provide a lazily loaded Map
>          Map map = new HashMap();
>          Set<Map.Entry> entries = cacheAdapter.toMap().entrySet();
>          for (Map.Entry entry : entries) {
>             Object key = entry.getKey();
>             if (!CacheHelper.isEvictAllNotification(key)) {
>                map.put(key, entry.getValue());
>             }
>          }
>          return map;
>       }
>       return Collections.EMPTY_MAP;
>    }
