> Currently Zero VM does not implement -XX:+LogTouchedMethods runtime features, which makes `runtime/CommandLine/PrintTouchedMethods.java` tier1 test fail with it.
> 
> Instead of implementing it (risking performance and rare bugs), Zero should just reject the option. 
> 
> Additional testing:
>  - [x] Eyeballing failure message
>  - [x] Affected test does not run with Zero anymore
>  - [x] Affected test still runs with Server
