Something like this should work:

mx vm -XX:+UseJVMCICompiler -jar $HOME/jcstress/tests-custom/target/jcstress.jar

To double check that Graal is compiling the relevant methods:

mx vm -XX:+UseJVMCICompiler -Dgraal.PrintCompilation=true -jar $HOME/jcstress/tests-custom/target/jcstress.jar

And, as always, to see the java launcher command being issued by mx, use the -v option:

mx -v vm -XX:+UseJVMCICompiler -jar $HOME/jcstress/tests-custom/target/jcstress.jar
