test script


Running this script on a real (non virtual) Windows machine works fine. I've
never had an error yet. At least in the several dozen times I've run it never
experienced an error.

However tunning this script on a Windows virtual machine I get the following 2
types of errors and warnings intermittently. More often the AccessDenied trace
than the FileSystemException.

AND always receive warnings of this type when the script is run:

due to 'E:\udu\DDD\fA714: The requested operation cannot be performed on a file

My guess is this has more to do with the JVM interaction with the VM than Ant.
And I'm aware that my problem here is that I'm copying to the same destination
using multiple threads. In the real world this is separate Ant builds copying
to the same destination independently, so it's not as easy to simply just not
do as in this trivial concoction.
