[jira] [Created] (LUCENE-5861) CachingTokenFilter should use ArrayList not LinkedList

David Smiley created LUCENE-5861:
------------------------------------

             Summary: CachingTokenFilter should use ArrayList not LinkedList
                 Key: LUCENE-5861
                 URL: https://issues.apache.org/jira/browse/LUCENE-5861
             Project: Lucene - Core
          Issue Type: Improvement
          Components: modules/analysis
            Reporter: David Smiley
            Assignee: David Smiley
            Priority: Minor


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.
