--------------------------------------
Hi Karl,
thank you for your comments and your new patch! I actually updated you initial
patch a couple of days ago to apply cleanly on the current trunk as I found it
quite simple and straightforward.
I have a question regarding the new patch: What kind of use cases do you have
in mind with the cached field? I would think that a TokenStream will only be
read once by the DocumentWriter? Currently you can add a field with a Reader,
and as far as I know is it not guaranteed that a Reader supports reset(), which
means it can only be read once, too. Thoughts?
