The reason I raised that point was becuase I am using a Coherence cache.
And I am implementing the getAll - putAll method etc... into a brand new
plugin for OpenJPA.
But I think that for anyone else that create an OpenJPA plugin for their
favorite cache product - this would give them the ability to do the right
thing.
I hope this goes through very soon in the code...

That's right, that the code here (transformToVersionSafePCDatas) should
call
cache.containsAll() or cache.getAll(). That way, it will save a lot for
any
data cache that provide getAll(). It won't gain much for OpanJPA "native"
data cache since it is delegated to AbstractDataCache.getAll() (ln. 449)
which loops thru the list to get the objects from the cache. However, it
save the traffic if any.
