Are you trying to run this bug's test (which has nothing to do with
CMS)? Or are you talking about 8209835 "Aarch64: elide barriers on all
volatile operations" (which runs some subtest with CMS)?

Anyway, I updated to current jdk/jdk, rebased, rebuilt and I can run the
tests of both bugs fine with:

jtreg -ignore:quiet -conc:8 -dir:<path to jdk>/test/hotspot/jtreg -compilejdk:<path to jdk>/build/linux-aarch64-normal-server-fastdebug/images/jdk -testjdk:<path to jdk>/build/linux-aarch64-normal-server-fastdebug/images/jdk -va -javaoptions:'-server' compiler/c2/aarch64/

and

jtreg -ignore:quiet -conc:8 -dir:<path to jdk>/test/hotspot/jtreg -compilejdk:<path to jdk>/build/linux-aarch64-normal-server-fastdebug/images/jdk -testjdk:<path to jdk>/build/linux-aarch64-normal-server-fastdebug/images/jdk -va -javaoptions:'-server' compiler/unsafe/CASandCAEwithNegExpected.java
