Ohh, I remember this now. Yeah, this is getting nowhere indeed.
Ask the same question multiple times, you get the same answer :)

Jokes aside, I don't know what to tell you about the problem on Windows.

How about trying Google ?
The third link [1] returned by this [2] refers to the info you need:

   "To use this, invoke Java with the System property 
org.apache.lucene.FSDirectory.class set to 
org.apache.lucene.store.MMapDirectory. This will cause 
FSDirectory.getDirectory(File,boolean) to return instances of this class."

And, of course, there is [3]. Looking further down on the google matches, I 
found this interesting match [4] as well. Look in the second half, the 
forwarded message.
