> EhCache often has a bit of lag time when invalidating expired cache elements, first setting the Element value to null and then removing the key. If you are hitting a cache rapidly one often will run across a key that is present in the cache that still has a null element entry.
> The logic for successfully key retrieval just needs to be slightly tweaked to check for null values.
