I don't know if you have tried to run the unit tests that in the test/java/nio/file/WatchService directory but it would be interesting to see if it passes these tests.

The WatchService is slightly different in it's implementation from the current java WatchServices, so I'm not sure you would want that. Of course I would be happy to see it included but having just got it to where it passes a few unit tests I'm not that confident it's ready for that.
The openjdk WatchService directory has a Basic test class which it does as of just now, pass. Which is why I decided it was ready to be considered more or less a release worth telling anyone about.
I was going to try some of the other unit test classes. I added the LotsOfEvents test but mine doesn't seem to get anywhere with that. No debugging yet. A little more about this is in the project known_issues.txt file.
