Look goods.

A possible problem is the unmatched method names. Generally, the method `Files.createSymbolicLink` may match `TestUtil.supportsSymbolicLinks` instead of `TestUtil.supportsLinks`. And the `Files.createLink` may match `TestUtil.supportsLinks` or `TestUtil.supportsHardLinks`. But they are just test code, so I think the current patch is OK.
