IOException - The handle is invalid

Hi,

I'm running load tests with Lucene 2.0, SUN's JDK 6 on Windows XP2, dual core
CPU. I have 8 worker threads adding a few hundred K documents, split between
two Lucene indexes, I've started getting

java.io.IOException: The handle is invalid in places like

java.io.RandomAccessFile.writeBytes(Native Method)

I saw Mike McCandless JIRA issue

http://issues.apache.org/jira/browse/LUCENE-669

Is the patch referenced there useful for a 2.0 system. I would like to use the
lockless commit stuff, but am waiting until I get the core system working well.

I am also getting IOException in some of my classes, but from the JIRA comments,
it seems that Lucene may be the culprit.

No urgency, I won't get a chance to test it until the New Year, but it's easy to
reproduce, although intermittent.

Antony
