Wrong exception thrown?

[John Hendrikx]

Exception in  thread "Thread-8": java.nio.file.AccessDeniedException:
c:\Copy\Macros2 -> c:\Copy2\Macros2
	at
sun.nio.fs.WindowsException.translateToIOException(WindowsException.java:83)
	at
sun.nio.fs.WindowsException.rethrowAsIOException(WindowsException.java:97)
	at sun.nio.fs.WindowsFileCopy.move(WindowsFileCopy.java:301)
	at sun.nio.fs.WindowsPath.implMoveTo(WindowsPath.java:1004)
	at sun.nio.fs.AbstractPath.moveTo(AbstractPath.java:201)
	at
hs.filemanager.transfer.RenameFileVisitor.rename(RenameFileVisitor.java:67)

This occurs when moveTo() is called with the arguments indicated +
ATOMIC_MOVE.

I would expect the FileAlreadyExistsException to be thrown.  It's not a
permission issue (and the files are not 'read only').
