[infinispan-dev] Abstracting javax.cache.annotation.CacheKey away from the user?

Pete/Kevin,
Looking at the Infinispan CDI quickstart, I see:
@GreetingCache
private Cache<CacheKey, String> cache;
The key that the user really uses here is String. So, could that be defined like this?
@GreetingCache
private Cache<String, String> cache;
Btw, I've just tried this and when using the key I get:
Caused by: java.lang.ClassCastException: org.infinispan.cdi.interceptor.DefaultCacheKey cannot be cast to java.lang.String
Are we forcing the user to dephicer what's in CacheKey? Related to this, looking at org.infinispan.cdi.interceptor.DefaultCacheKey I see no way to retrieve individual elements of a key.
My point here is whether we can avoid leaking javax.cache.annotation.CacheKey to the user cos it can do little with it without being able to get its contents.
I see there;s a way to define a custom key, but that should not be necessary for a simple key based on a String for example.
Cheers,
