jar always follows symbolic links and as far as I know there is
no option to prevent it from doing so. So if you have a symlink
in your filesystem like "lib -> .." you throw jar into an infinite

By default tar does not follow symbolic links. Also zip provides a
way to not follow symlinks (-y).
I consider this a bug not an RFE since it is such a glaring omission.
