java.nio.file API with JDK 1.6 and older

[Alan Bateman]

Semen,

There have been a couple of projects started to get this API working 
with jdk6 but I don't know if anyone actually released anything. A 
non-technical snag is that the API would need to be in its own name 
spaces (can't be java.**).  Another thing to keep in mind is that the 
API isn't standalone as it includes changes in other areas 
(java.nio.channels in particular). Otherwise I think the only technical 
issue is that there are a dependencies on some JDK internal classes 
(such as sun.misc.Unsafe) that will require attention.

You asked about tests and I would expect the tests in 
jdk/test/java/nio/file/** will be useful. The test harness we use is 
jtreg [1] so you would need to change them if you wan to use JUnit or 
another test framework.

I can't help on the license questions.
