This is a known JDK issue with memory mapping a file.
The references may not be GC'd at the time the request to delete is
performed, and thus you will get an IOException.

Hoss Man commented on LUCENE-727:
---------------------------------
Can you inlcude a full stack trace of the exception so we can see
what code path causes this problem?
it would be even better if you could inlcude a JUnit test
demonstrating the problem.
MMapDirectory can't create new index on Windows
-----------------------------------------------
Key: LUCENE-727
URL: http://issues.apache.org/jira/browse/LUCENE-727
Project: Lucene - Java
Issue Type: Bug
Components: Index
Affects Versions: 2.0.0
Environment: Windows XP, JDK 1.4
Reporter: benson margulies
When I set the system property to request the use of the mmap
directory, and start building a large index, the process dies with
an IOException trying to delete a file. Apparently, Lucene isn't
closing down the memory map before deleting the file.
