test/hotspot/jtreg/applications/jcstress/README line 35:

Suggestion:

You should specify the JAR location by passing the following property when invoking jtreg. For example:
-Djdk.test.lib.artifacts.jcstress-tests-all=jcstress-tests-all-20241217-2035.jar

Though I'm unclear if this is a setting passed directly to jtreg, or whether it should be set via e.g. `-javaoption:-Dxxx` ?
