Hmm, but you swap these files over while an IndexReader is still open on the index? And then you call openIfChanged? If so, that's what's leading to this exception: you shouldn't ever need to overwrite files at index level. Instead, use IndexWriter.deleteAll, then index all your new docs, then commit, then reopen the reader. Alternatively, open IndexWriter with OpenMode.CREATE on the index, index all your docs, commit, and reopen. Separately, it's better to use a near-real-time IndexReader so you don't have to commit in order to see changes.
