In the current implementation of the MetaData,
I've decided not to cache misses.
i.e. if you do
MetaData.getAnnotation(DoesNotExist.class)
it doesn't cache the "non-existance".
I think it would be advantageous to do so?
i.e.code that repeatedly asks for non-existant metadata will be faster
The disadvantages are:
* Bad code could fill the cache with redundant misses
* Removal (e.g. undeployment) of metadata will require a full
cache flush for relevant contexts rather than currently which
just invalidates the individual item.
Thoughts?
