I'm pretty sure you're supposed to reuse *all* Field instances, for optimum performance. Though admittedly this is quite tricky to do right if you have multiple fields with the same name in the document where the number of fields might change for each document you add. If you only have one of each, just add all the fields to the document once and keep a reference to them, then just set the value on each before doing your addDocument.
