    Description

      CachingTokenFilter, to my surprise, puts each new AttributeSource.State onto a LinkedList. I think it should be an ArrayList. On large fields that get analyzed, there can be a ton of State objects to cache.

      I also observe that State is itself a linked list of other State objects. Perhaps we could take this one step further and do parallel arrays of AttributeImpl, thereby bypassing State.
