The changes to UnixCopyFile.java will break copying of sym links (in 
Files.copy you'll see that it is specified to support NOFOLLOW_LINKS). 
The implementation doesn't depend on O_NOFOLLOW support so I don't think 
any changes are required.

UnixChannelFactory.java L224 - this needs to throw UnixException rather 
than UOE. This will be handled and translated into the appropriate 
IOException (actually FileSystemException).

Otherwise the changes look okay to me.
