Yonik Seeley commented on LUCENE-415:
-------------------------------------
the fact that getChannel has side effects in Windows makes me a little
uncomfortable about what other side effects it has on other platforms. Is it
only needed when truncating a previously existing file, or is it always needed
to solve "fairly odd but repeatable issues with stale/invalid file handles
under windows XP"?
If the former, we could do the following:
public FSOutputStream(File path) throws IOException
{
file = new RandomAccessFile(path, "rw");
if (file.length()!=0) {
file.setLength(0);
file.getChannel().close(); // solved some fairly odd but repeatable
issues with stale/invalid file handles under windows XP.
}
}
