[~stephen], The upcoming release of Ivy requires Java 7 as a minimum version. So I went ahead

> If a user switches between "use symlinks" or not (or, say, has ant/ivy configured with
symlinks but Eclipse/IvyDE without symlinks), the ivycache can be corrupted.
> Specifically, if a symlink was setup in symlink mode:
> lib/foo.jar --> ivycache/com/foo/foo-1.2.jar
> And then later we retrieve into lib without symlink mode, Ivy retrieve will write, say,
foo-1.3.jar's bytes into the lib/foo.jar location...which will then overwrite the foo-1.2.jar
bytes in the ivycache.
