Andy Hind commented on LUCENE-415:
----------------------------------
We have tested the above solution pretty heavily since 18/11/2005 and would
regard it as stable in 1.4.3.
Looking at the 1.9 code stream the issue is likely to be present, unless there
is some other code that checks if an index segment file already exists when not
expected, or the next segement is generated based in the segments that actually
exist in the directory.
In 1.4.3 ..... in FSDirectory
......
final class FSOutputStream extends OutputStream
{
RandomAccessFile file = null;
public FSOutputStream(File path) throws IOException
{
file = new RandomAccessFile(path, "rw");
file.setLength(0);
file.getChannel();
}
......
will sort this issue and some other file handle issues I have seen under XP
Something similar is likely to be required in FSIndexOutput in the 1.9 code

> I've been batch-building indexes, and I've build a couple hundred indexes
