Hello all,
I am currently trying to test graal using shenandoah gc.
i follow the instructions bellow:
on the jdk :

bash configure --with-boot-jdk=/opt/jvms/jdk-14.0.2 --with-jtreg=/opt/jtreg

make graal-builder-image

make run-test TEST="hotspot/jtreg/gc/shenandoah"

export JAVA_HOME=path/to/jdk/build/linux-x86_64-server-release/images/graal-builder-jdk

/opt/jtreg/bin/jtreg -v -vmoptions:"-XX:+UseShenandoahGC
-XX:ShenandoahGCMode=passive -XX:+UnlockDiagnosticVMOptions
-XX:+UseJVMCICompiler" ~/jdk/test/hotspot/jtreg/gc/shenandoah

and the output is:Test results: no tests selected

When i change the tests path from




it starts running all the tests located there and my professor who
used the same instructions had it working fine.
