@zzambers
Generally we want to get away from `@requires vm.compiler2.enabled`, because it means tests are only run on C2 and not other compilers. For example if C2 is disabled and we only have C1. Or only interpreter. Or Graal ...

Why not just add the compile flag `-XX:-IgnoreUnrecognizedVMOptions`? That could be a good alternative for most cases, I think.
