I installed Mavericks and everything is working fine. Perfectly in fact. Decided to open up disk utility and check permissions as I do before and after a OS install. I got this one, Group differs on Library/Java; should be 0; group is 80.Permissions differ on Library/Java; should be drwxr-xr-x ; they are drwxr xr-x . I don't have Java installed, as far as I know.. I don't need it. Is this something I should be concerned about?
