CachingNormalizer - where does it caches?

The constructor accepts a cachesize which is never used. Apart of this I
really can't see, where the caching happens.

Any ideas?

It really would be nice if we can get this cache mess sorted out and have a
solid entry cache in place before releasing 2.0. It's a critical part of the
server and should not be difficult to do with ehcache or something.  If we
can get this JDBM serialization hook working to check the cache first that's
another plus.

Thoughts?

Ok, in real world, this cache is just useless. I mean, it's a good idea 
to think about having a cache, but it has to be implemented correctly, 
which is not the case here.

The discussions we had a while back about the caches (and there is a 
JIRA about it) demonstrated that we need a global cache, based on some 
global system like JCS (apache commons-jcs). It should be linked to the 
DirectryService, and mus not be a singleton.

Right now, the cache we have are associated with instances of the 
interceptors, so they are not shared. They are just valid during an user 
session, AFAICT. Not efficient... (I would ask you to take this with 
cautious, I may be wrong).
