I've done some more sniffing on the Lucene list, and noticed that Otis made the following comment about a FileNotFoundException problem in late 2005:
Are you using Windows and a compound index format (look at your index dir - does it have .cfs file(s))? This may be a bad combination, judging from people who reported this problem so far. (http://www.nabble.com/fnm-file-disappear-td1531775.html#a1531775) Again, a CFS index was indeed involved in my case, but my experience comes almost three years after Otis' message...
