Looked into `os.family` and this one indeed seems to work ok (there are tests using it in tier1 and they seem to be correctly selected based on OS). Note however that `@requires` requires some caution on JDK8 as not everything works. There was a problem with `vm.bits`, which has shown no errors, but tests got skipped on all platforms (even when supposed to be enabled)  [1].
