Would it be a good idea if we add this Windows limitation to the NIO javadocs somewhere, say in the FileChannel class? I spent a lot of time chasing this down until I finally figured out it was a known issue. --Sean On 6/27/11 9:19 AM, Alan Bateman wrote: Sean Mullan wrote: Several jigsaw unit tests are failing on Windows because of bug 4715154 [1] which was closed a long time ago as "Will Not Fix".

Thanks, Sean [1] http://bugs.sun.com/bugdatabase/viewbug.do?bugid=4715154 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. -Alan
