Also, I see you added metal.
I think I'm going to request an extra layer on top of what I previously suggested.

It is possible to have multiple @test tags, not just @run tags, so you can do platform-specific things on just the specific platform, so it would become

 /* @test 
    @requires("os.name"="windows")
   @run main/othervm -Dsun.java2d.d3d=false
   @run main/othervm -Dsun.java2d.d3d=true
*/

 /* @test 
    @requires("os.name"="macos")
   @run main/othervm -Dsun.java2d.d3d=false
   @run main/othervm -Dsun.java2d.metal=true
*/


 /* @test 
    @requires("os.name"="linux")
   @run main/othervm -Dsun.java2d.xrender=false
   @run main/othervm -Dsun.java2d.xrender=true
*/

and finally the one that is cross-platform AND defaults
 /* @test 
   @run/main/othervm
   @run main/othervm -Dsun.java2d.opengl=false
   @run main/othervm -Dsun.java2d.opengl=true
*/
