Wierd Coherence bug with keySet() / entrySet() not returning all data.

Question

So I have a cache with 3 key/values in it.
If I call cache (over extend) with specific keys, i get all values back.
Object valueA = namedCache.get("A");
Object valueB = namedCache.get("B");
Object valueC = namedCache.get("C");
i.e. valueA/B/C are all not null.
If I now try to use keySet()/entrySet(), I only get 1 value back.
eg:
int cacheSize= namedCache.size(); //cache size is 3
int keySetSize = namedCache.keySet(); //cache size is 3
int actualKeySetSize = (new HashSet(namedCache.keySet())).size(); // actual size is 1
The same happens if I iterate over keyset/entryset, i.e. there is only 1 value in the result.
I have 2 storage nodes, JMX shows 1 node has 1 unit and other node shows cache has 2 units.
Are there any known bugs where above can occur, we are using Oracle Coherence GE 3.5.3/465p3.
i.e. keySet/entrySet not returning full result sets!
Cheers,
Neville.

Apparently a timing issue between the "creation" of a cache, and the processing of requests against that cache. Because of the nature of the cache creation protocol, it is possible for the client creating the cache to return before all storage members have been notified of the cache name. It is therefore possible for cache requests to arrive at a storage member before that member has had a chance to instantiate its backing map.
Fix is part of 3.6.0 GA, and is now slated to be back ported for 3.5.3p8.
Have tested against 3.6 and all looks ok now.
