      Description

      Improve access time for loaded class cache (system dictionary).

      ..is it possible that the internal data structure might one day change from monolithic hash table to something more hierarchical? For example having a separate data structure per package or per classloader. I was reading online about something called a HAT-trie that deals with shared prefixes and was designed with cache locality in mind.
