Note that @requires can’t cope with multiple @run lines with differing requirements.  I just ran into this with a test that needs to be run against either G1 or CMS.  Rather than one test with multiple @run lines, I needed to use multiple tests, each with a single @run line and corresponding @requires constraint.
