> Shai just reported this on the dev list.  Simple test:
> {code}
> Directory dir = new RAMDirectory();
> IndexWriter writer = new IndexWriter(dir, new SimpleAnalyzer(), MaxFieldLength.UNLIMITED);
> writer.setInfoStream(System.out);
> writer.addDocument(new Document());
> writer.commit();
> writer.close();
> {code}
> hits this:
> {code}
> Exception in thread "main" java.io.FileNotFoundException: _0.prx
>     at org.apache.lucene.store.RAMDirectory.fileLength(RAMDirectory.java:149)
>     at org.apache.lucene.index.DocumentsWriter.segmentSize(DocumentsWriter.java:1150)
>     at org.apache.lucene.index.DocumentsWriter.flush(DocumentsWriter.java:587)
>     at org.apache.lucene.index.IndexWriter.doFlushInternal(IndexWriter.java:3572)
>     at org.apache.lucene.index.IndexWriter.doFlush(IndexWriter.java:3483)
>     at org.apache.lucene.index.IndexWriter.flush(IndexWriter.java:3474)
>     at org.apache.lucene.index.IndexWriter.addDocument(IndexWriter.java:1940)
>     at org.apache.lucene.index.IndexWriter.addDocument(IndexWriter.java:1894)
> {code}
> Turns out it's just silly -- this is actually an issue I've already fixed on the flex
(LUCENE-1458) branch.  DocumentsWriter has its own method to enumerate the flushed files and
compute their size, but really it shouldn't do that -- it should use SegmentInfo's method,
instead.
