FNFE hit when creating an empty index and infoStream is on
----------------------------------------------------------
Key: LUCENE-2045
URL: https://issues.apache.org/jira/browse/LUCENE-2045
Project: Lucene - Java
Issue Type: Bug
Components: Index
Reporter: Michael McCandless
Assignee: Michael McCandless
Priority: Minor
Fix For: 3.0
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

{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.
