Doron Cohen commented on LUCENE-937:
------------------------------------

Good catch, patch look good to me.
It makes sense to modify anyhow, but just wondering, - what is the performance difference?

While we're looking at this, I noticed three other uses of LinkedList that can be changed
to ArrayList: 
  - DocumentWriter
  - CompoundFileWriter
  - MultipleTermPositions

> The wrong data structure was used for the CachingTokenFilter. It should be an ArrayList
rather than a LinkedList. There is a noticeable difference in speed.
