Several jigsaw unit tests are failing on Windows because of bug 4715154 [1]

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.
It isn't only deleting the file that causes problems. If you try to subsequently
open the file and do other operations on it, they can fail, and we do this when
signing jmod files.
We may be able to avoid calling FileChannel.map. I'm looking more into it ...
