This is a limitation of Windows and I'm not aware of any way to create a 
file-mapping that would allow the file be deleted while the mapping 
exists (if there is a way then it would be great to know about it).  In 
a couple of tests we've had to do an ugly System.gc() + short sleep at 
the end of the test to trigger the unmap.
