Just a quick question on how this should behave.
Lets say you had 100 threads all try to get from a cache with the same key, would it call the CacheLoader 100 times for the same key or once and return null for the next 99 until the item is fully loaded?
It would call the loader 100 times.
If you want more sophisticated behaviour use SelfPopulatingCache, which will block the other requests while the first one does the work.
This is yet one more thing we need to toss around in the EG. From the point of view of protecting backing resources the blocking approach is much better.
