There're huge performance improvements in Infinispan compared to JBoss Cache, regardless of TreeCache itself. There're improvements as well in the way Infinispan implements TreeCache structure. Instead of keeping hashmaps of hashmaps, the entire tree structure is kept in a single map which is a lot more memory efficient.
By FQN grouping I suppose you talk about keeping a map of things mapped to a key. If this is so, Cache.put(key, Map) should do the trick. What's the write skew issue you had? Could you post a unit test?
